Let the great Dex debate begin! As we posted last week, "Melrose Place" stud Colin Egglesfield has been cast to play Dex Thaler, the main love interest in the big screen adaptation of the chick lit book "Something Borrowed." Colin, who certainly fits the physical description of the character (read: unbelievably handsome), beat out the likes of "Twilight" actor Peter Facinelli (both pictured), who seemed none-too-happy about the decision. Peter tweeted today, "What?! I didn't get DEX?! R they on crack? lol Its ok. Instead of S'mthing Brrwd I'm doing S'mthing else.A movie I wrote.Thanx 4 the support." Author Emily Giffin later responded, "Sorry to all the PF fans. Guess it wasn't meant to be."
Peter's "New Moon" costar Daniel Cudmore was also a-Twitter today. He campaigned for the 2010 MTV Movie Awards. Daniel argues that his brief, but brutal (poor Edward!) battle with Robert Pattinson is worthy of some golden popcorn, posting, "I do believe that Rob and I's little tussle deserves a vote for best fight at the MTV awards, don't you think!?" You can still vote for which movies and moments you think should be nominated here!
