The producers of 90210 don't want their steamy starlets getting too tan!

In fact, according to FoxNews.com show runners have already put Jessica Lowndes on a "tanning time out!" 

"AnnaLynne (McCord) was telling a few people at an Emmy gift suite that producers have been giving everyone hell for their obsession with sun-kissed skin, and they've even banned Jessica from any tanning of any kind, whether it's from natural sunlight, tanning salon beds or a spray-on tan," a spy told Fox.

"AnnaLynne was just glad she wasn't targeted. She said she looks forward to her Fake Bake spray tan every time she gets it."

BUT "Apparently Jessica was not pleased and complained to AnnaLynne about it," the source divulged.

"She doesn't want her skin to turn a pasty white while AnnaLynne stays beautifully bronzed!"

Maybe they're expecting the show to run, like, a ba-zillion years and don't want crinkly, wrinkly stars - AS IF?
