Twihards know by now that Peter Facinelli, who plays Dr. Carlisle Cullen in the Twilight Saga, wants to see a grown man by the name of Rob DeFranco walk down Hollywood Blvd. in a bikini, singing "Single Ladies" by Beyonce. It's part of the bet he made with his best bud, DeFranco (@211me) last week upon joining Twitter.

Peter Facinelli The Details:
Rob DeFranco bet Peter Facinelli that he couldn't get 500,000 followers by Friday, June 19 -- a week's time. Peter, banking on the strength of Twilighters no doubt, accepted, of course.

If Peter wins:
DeFranco takes a walk of shame down Hollywood Blvd., holding up a sign that says "Twitter me," and Peter will be there to capture his "Single Ladies" crooning friend on video. (We're sure a bunch of other fans will show up to witness the momentous occasion as well.)

If DeFranco wins:
Peter will have to give his chair backing with his name on it from Twilight to DeFranco – which would kinda blow because he says that Rob's not even a fan. So our favorite vampire doctor decided to make things a little more interesting...

Here's where Twilighters come in:
If Peter wins the bet, he'll give away his chair backing to one of his followers. He hasn't stated exactly how yet, but he tells MTV he likes riddles; he might use one to decide. The hours are whittling away and Peter hasn't hit 300,000 followers as of 4:30 PST (but he claims Twitter's counter was broken last night). We'll see if his plans for DeFranco's bikini walk come to fruition soon enough. If you want to help him out, or be in the running for his chair backing, or just see the guy humiliated all in the name of good fun, follow Peter Facinelli now!
