We love when the world's hottest pop stars let us have a peek into their lives through their camera phones. In this week's collection of Twitpics, Chris Brown showed off a new pair of shoes he just got, fresh out of the box. The caption on his pic read just "McNasty," though we're not sure whether Breezy meant his shoes or his mean mug, but we think he looks as tough as ever -- and when you're a hip-hop star, that's a great thing. Also in our Twitpics gallery, brother trio Hanson stopped into NYC to perform a set for VH1, while Ashanti rehearsed for tour and Chris Martin of Coldplay rode a unicycle for the new 'Paradise' video. Speaking of videos, 'The Voice' runner-up Dia Frampton gave a few peek shots from the set of her 'The Broken Ones' video shoot. Check out these insightful Twitpics and let us know which is your favorite this week!
