United Kingdom, Feb. 6 -- Kristin Davis was under so much pressure to stay slim on 'Melrose Place' that she fainted from her intense diet and exercise regime.

The 59-year-old actress got her big break in 1995 when she was cast on the show as Brooke Armstrong and she recalled there was a "difficult" vibe on the set because of the unrealistic standards of beauty that female cast members were expected to uphold.

She told People magazine: "There was a general vibe on the set though, that was difficult, about the thinness situation."

"Every single person was gorgeous and super skinny. So I was like, 'This is what I have to do.'"

Kristen hired a running coach and would take part in back-to-back 90-minute spin classes, but was barely eating....
