This week on Twitter, Scotty McCreery visited 'the place where it all started' -- the Bradley Center in Milwaukee, where he first auditioned for 'American Idol' -- and he had a Twitpic to prove it. Elsewhere, in Miami, Bow Wow hung out with the legendary Lil Wayne at the King Of Diamonds club and tweeted a pic, while Vanilla Ice rubbed elbows with Adam Sandler on a movie set and shared that with his Twitter followers. Bieber's do-gooder girlfriend Selena Gomez stopped in at Ryan Seacrest's Ryan Foundation for ill & injured children, and Willow tweeted a Twitpic that showcased her ballet skills. Sorry, she was not whipping her hair back and forth.
