Mark Teixeira and Alex Rodriguez filmed cameos on “Entourage” at the Stadium Wednesday afternoon.

Both Yankees will play themselves on the HBO show, where the story depicts them as investors in Queens Italian restaurant Don Peppe, which Jerry Ferrara’s character, Turtle, attempts to bring to Hollywood.

It was reported last month that “Entourage” creator Doug Ellin had written in cameos for Rodriguez, Teixeira, Amar’e Stoudemire and Don Peppe — where Ellin’s a real-life regular — for the show’s eighth season, its last.

Last weekend, Teixeira upstaged a shoot at the Equinox gym in West Hollywood when he stopped by to visit Ellin. A spy said gym-goers seemed unfazed by the rolling cameras and appearances by cast members Kevin Dillon and Rex Lee — until the Yankee first baseman popped in. “Everyone’s neck craned to see Mark,” a witness said. “The shoot became more about the Yankee visiting LA rather than the production.”

“My trainer suggested I try Vita Coco because of all the electrolytes and potassium,” said A-Rod in a statement announcing he’ll appear in ads for Vita Coco.

“Now I drink it every day.” But A-Rod has been an investor in Vita Coco’s competitor, Zico, for more than two years, according to Zico CEO Mark Rampolla.

He only learned that A-Rod had struck a deal to promote his rival when a Vita Coco press release went out yesterday. “I was definitely surprised,” said Rampolla. He wouldn’t disclose the size of Rodriguez’s investment, except to say, “At his level, it’s not a make-or-break [amount], but most people would love to be able to make an investment like that.”

A-Rod’s manager, Guy Oseary, and his ex, Madonna, are both investors in Vita Coco. Rampolla said he would be “happy to give A-Rod his money back.” But one source familiar with A-Rod’s move said, “It’s like betting against your own team.”

Oseary didn’t get back to the media. A-Rod’s rep declined to comment.

The ‘Bad Teacher’ actress only confirmed she was dating the baseball star last month even though they had been together for over a year but pals have now claimed the pair have decided to split.

A source told gossip blogger Perez Hilton: “They’ve broken up. [Cameron] is hurt and betrayed, because she tried so hard to please him… She went overboard.”

Although the couple had been inseparable for the past year, the 38-year-old beauty has previously claimed she is in no rush to settle down.

When quizzed about her thoughts on marriage and children, Cameron – who has dated a string of Hollywood hunks, including Justin Timberlake, Jared Leto and Matt Dillon – said: “What about it? If I say, ‘This is how I’m going to live my life,’ I am closing myself off to all these other possibilities. I’m the kind of girl who likes to be open to every possibility, who is open to all my options.”

The stunning actress has been dating the baseball star for around a year and Alex is now ready to make things official after being introduced to her mother, Billie.

A source said: “Alex is very loving toward Cameron and protective of her. She loves that he’s such a family man.”

According to InTouch magazine, Alex – who has introduced Cameron to his two children, Natasha, six, and three-year-old Ella, from his marriage to Cynthia Scurtis – has been shopping for engagement rings at an upmarket New York jewellers.

Cameron proved her commitment to Alex and his daughters by recently moving to Miami to be closer to them.

Although she may now be considering marriage, the 38-year-old beauty has previously claimed she is in no rush to settle down.

When quizzed about her thoughts on marriage and children, Cameron – who has dated a string of Hollywood hunks, including Justin Timberlake, Jared Leto and Matt Dillon – said: “What about it? If I say, ‘This is how I’m going to live my life,’ I am closing myself off to all these other possibilities. I’m the kind of girl who likes to be open to every possibility, who is open to all my options.”

From the undisguised delight on her face, it’s clear Cameron Diaz is proud of her man.

The delighted actress flew to the Dominican Republic with new boyfriend Alex Rodriguez yesterday to cheer him on as he was honored for his baseball skills at a special award ceremony.

Wearing a pretty white blouse, skirt and simple gold jewellery, Cameron, 38, stood out from other members of the audience at the second annual induction ceremony of the Latino Baseball Hall of Fame.

The Green Hornet actress smiled and looked proud of her New York Yankees boyfriend.

She was also snapped whispering into the ear of a smiling Alex, who looked sharp and sophisticated in a grey suit, white shirt and black tie.

The 35-year-old Yankees third baseman, whose parents are Dominican, was honoured as the youngest player to reach 600 home runs.

While former Seattle Mariners hitter Edgar Martinez was inducted into the prestigious Latino Baseball Hall of Fame at Casa de Campo in La Romana.

Lately things have been heating up for Cameron and her baseball player boyfriend.

The couple spent several days last week hunting for a love-nest in Miami Beach, Florida, showing their relationship is more than just a passing phase.

They looked at a very large house currently being built on North Bay Road, an up scale and wealthy enclave of mansions.

If the couple move in, they will have some very famous neighbours – the area is home to celebrities such as Ricky Martin, Matt Damon, Bee Gees singer Barry Gibb, and film director/producer Michael Bay.

A typical California beach girl, Cameron Diaz revealed her excellent paddle surfing skills as well as her trim and toned body during a day on the water in Los Cabos, with her boyfriend Alex Rodriguez.

Cameron, 38, and A-Rod, 35, are spending their Christmas holiday with the baseball star’s two daughters, Natasha, six and Ella, two.

While the couple have been spotted poolside at their Los Cabos hotel with the little girls, it was an adults-only day as Cameron donned yet another bikini.

This time the Something About Mary star wore a simple brown two-piece as the pair headed out into the crystal blue waters.

Keeping herself shielded from the sun with a grey visor, Cameron paddled out on a yellow surfboard before standing up and balancing on her board like a pro.

The self-confessed tomboy has always been a keen surfer, and proved that she could Hang Ten with the best of them when she filmed the Charlie’s Angels movies.

Following some time paddling, Cameron attempted to jump onto a blue and white jet ski. The actress almost lost her balance for a moment but quickly picked herself up.

After donning a life jacket, Cameron appeared to get the hang of the jet ski and was all smiles as she sped along the water.

Cameron and A-Rod have been looking very cozy these days.

Cameron Diaz and Alex Rodriguez still haven’t spoken publicly about their relationship, but when a picture’s worth a thousand words, they don’t need to.

The couple, linked since February, was photographed Friday acting quite affectionate toward each other during a stroll in Miami.

In their boldest PDA to date, Diaz and Rodriguez walked arm-in-arm, with smiles plastered on both their faces.

As they stood by the water, the 38-year-old actress was pictured with her arms draped around the Yankees slugger, 35.

Though Rodriguez spends most of his time in Miami during the offseason, he and his gal pal were in town this particular weekend for the Saturday wedding of Yankees outfielder Nick Swisher and actress Joanna Garcia.

Diaz and Garcia became friends when they were dating Justin Timberlake and Trace Ayala, respectively, a few years ago.

Alex Rodriguez was spotted flirting with “Real Housewives of New York” star Kelly Bensimon at Wall in Miami the other night.

At the Art Basel party hosted by Vito Schnabel, Alex Dellal and Stavros Niarchos, “He had his arm ’round Kelly and they were flirting,” a witness said.

The next day the two were seen browsing art at the Convention Center. A different source said, “While Alex was recently seen with Cameron Diaz again, they’re not back together. He is single.” Reps for A-Rod and Bensimon didn’t get back to us.

Cameron Diaz and Alex Rodriguez fuelled speculation their relationship is firmly back on after spending Thanksgiving weekend together on a sun-soaked vacation.

The pair’s romance, which reportedly began back in February, was rumored to be in trouble last month when the Shrek star was pictured enjoying a night out with Glee’s Matthew Morrison, while a subsequent report from Life & Style magazine suggested the relationship was over.

However, Diaz and the sportsman were reportedly spotted enjoying each other’s company during a trip on a luxury yacht in Miami Beach, Florida last week, lying next to each other and sunbathing and chatting on the deck.

And their reported reconciliation continued over the Thanksgiving holiday – they were seen soaking up the sun in their swimwear in Mexico.
