Gossip Girl star Blake Lively has had a rough week, with alleged nude photos of her leaking on the internet just days before she was set to promote her new flick The Green Lantern at the 2011 MTV Movie Awards.

However, Lively's rep has insisted that the photos of Blake are 100% fake, and the gorgeous blonde still rocked the awards show with confidence in a beautiful electric blue Michael Kors dress!

Lively, who usually isn't afraid to show some skin in her red carpet looks, went for a more modest and subtle look last night, but she definitely proved she can rock even the simplest styles.  The 23-year-old pranced down the red carpet in purple Christian Louboutin shoes, and the only accessories she donned were an array of bangle bracelets on her right arm.  Fabulous!

While it was rumored that Lively was going to poke fun at her alleged nude photo scandal at the awards show, she kept it mature and professional and just stuck to promoting her new movie.  However, that doesn't mean the other stars in attendance didn't take their shot at making fun of her situation.

When host Jason Sudeikis was introducing Blake and her Green Lantern co-star Ryan Reynolds to the stage, he said that Reynolds would be joined by "Someone we believe is the real Blake Lively though she won't confirm it." 

Even America's Sweetheart and good-girl Reese Witherspoon took a jab at Lively when accepting the award show's biggest honor - 'The MTV Generation Award' - by saying, "If you take naked pictures of yourself with your cellphone, you hide your face!!"

Despite these comments though, Blake declined to answer reporter's questions about the photos.  What does she care what people think anyway, when she has new rumored boyfriend Leonardo DiCaprio to make things better!?
