POTW: Christina Aguilera, Justin Bieber, Rihanna, Nicki Minaj
First Yo Gabba Gabba! and now Disney. Christina loves posing with Max and plush, over-sized caricatures. Just as long as she leaves her Burlesque outfit at home, we're all for it. Christina Aguilera and son Max celebrate his 3rd birthday at the Disneyland Resort on January 11, 2010 in California.

Christina Aguilera and her son posed with the Disney clan, Justin Bieber got bruised, Rihanna and Nicki Minaj made silly faces, Gucci Mane got an ice-cream tat on his face, Amy Winehouse let the girls breathe, Jennifer Lopez smiled hard while Steven Tyler seemed disconnected, Cee-Lo and Samantha Ronson looked like bank robbers and Lil Jon celebrated his birthday with personalized cupcakes. It all happened this week and we've got the pics to prove it.
