Jessica Stroup says she appreciates the challenge of playing someone with a mental disorder.

The 23-year-old actress plays the bipolar Silver on the reincarnation of “90210″ on the CW network. The show’s second season makes its premiere Tuesday night.

Stroup says she’s careful not to play Silver’s mood swings too over the top.

She says she did as much research on the disorder as she could because “it’s something that touches so many people but isn’t really explored.”

Stroup says some people “have reached out to me to say they watched and it meant a lot.”

Like the original show from the 1990s, “90210″ follows a group of teenagers in Beverly Hills.

“90210″ will air at 8 p.m. EDT on the CW.

Beverly Hills, 90210 stars Jessica Stroup and Shenae Grimes are so thin that show producers and costars are poised to take action, Us Weekly reports in its latest issue, on newsstands now.

“They want the girls to gain weight,” a show source tells Us. “They are trying too hard to be skinny, and it’s started to wear on them. It’s just not healthy.”

Stroup, 21, is 5-foot-8 but weighs 100 to 105 pounds while Grimes, 18, is 5-foot-3 and stands at a mere 90 pounds, Beverly Hills-based weight-management expert Dr. Joyce Peters estimates to Us.

“I’ve never seen Jessica or Shenae eat,” another show source tells Us.

So shocking is the situation that their 90210 male costars are contemplating an intervention.

“I heard some of the boys on the show are going to sit down with the girls and talk to them,” an additional show source tells Us.

“The girls were all skinny when they started, but they’re definitely thinner now,” the source adds.

Check out the latest issue of Us Weekly for the full story behind the stars’ dramatic weight loss and the pressure to be thin on a hit show.
