POTW: Pete Wentz, Lil Wayne, Ke$ha, Justin Bieber

It takes a reaal man to dress up like an elf, even for a holiday portrait with son Bronx and wife Ashlee Simpson at the end of 2010. We'd bet dad was responsible for putting the kid in he Van Halen shirt though.

Pete Wentz, wife Ashley Simpson and baby Bronx took an awkward holiday photo, Lil Wayne got his bowl on, Ke$ha channeled Rob Zombie, Justin Bieber thanked the stars, Nick Cannon rubbed wife Mariah Carey's baby bump, Jay-Z and Oprah took a trip down under, Katy Perry became queen santa bee and President Obama recruited a cadre of artists with names starting with the letter "M." It all happened this week and we've got the pics to prove it!
