• Nicki Minaj channeled her inner Smurfette for the March issue of Vogue by posing in blue-hued skin.
• America's sweetheart Selena Gomez proved she also has a wild side when she debuted a tiny heart tattoo on her wrist this week.
• We saw a completely new side of Katy Perry when she tweeted a pic of her prison attendant character ensemble for Raising Hope. Two words: Hairy. Lip.
• Rihanna celebrated her birthday this weekend in not one, two, three, but FOUR fash-filled ensembles. RiRi + her wardrobe = the gift that keeps on giving.
