Megan Fox comes out to support her on-and-off-again fiance Brian Austin Green (The Sarah Connor Chronicles) at the FOX TCA Summer Party at the Santa Monica Pier in Santa Monica, Calif., on Monday.

The 22-year-old actress was forced to gain 10 pounds in three weeks for her role in the second Transformers movie following a dramatic and dangerous weight loss for her last film, Jennifer’s Body.

“I should have toned up for Transformers but I’m really lazy. I had to put on weight,” she told Pop Tarts. “I’d lost a lot of weight and got really scrawny, but I was told I had to put on size for Transformers because Michael [Bay, the director] doesn’t like skinny girls.”

The Tranformers star recently told the Daily Star, “I would love to do a movie naked – it would be beautiful. No one dares make that kind of film today. They did it in the 1930s in an arty way, so why not now?”
