● Katy Perry signed her divorce papers with a big ole smiley face under her name. And probably with one on her face, as well. [Radar]

● M.I.A. won Madonna's Super Bowl half-time show when she punctuated her "Give Me All Your Lovin'" verse with a middle finger. She really "don't give a shit." [Rap-Up]

● Turns out Taylor Swift won't be playing Eponine in Les Miserables after all, as the role has been won by British actress Samantha Banks. Guess last week's London trip, purported to be for rehersals, was all about that dinner with Gwenyth and Chris. [JustJared]

● Katy Perry has unfollowed Russell Brand on Wwitter, but Russell Brand is, for now, still following Katy Perry. We can't all be like Demi. [Us]

● Newly single and free-to-be, Katy Perry has been voted the "most cheat-worthy" celebrity by the fine users of AshleyMadison.com. Vacation queen Rihanna, Mila Kunis, Salma Hayek and Jennifer Aniston follow, and Sarah Palin comes in at 10. [Radar]

Sign of the apocalypse: today, Electronic Arts announced that it's partnering up with Katy Perry for a special Perry-themed expansion pack of The Sims, which you remember for ruining your productivity for two weeks back in 2000. In a statement that is totally real and not at all the calculations of an algorithmic cyborg built to sell Gameboys to orphans, EA said, "Today marks the start of the most integrated and exciting collaboration with any artist in the history of The Sims. No performer could better represent the humor and fun of The Sims brand." It's like something right out of a Philip K. Dick novel!

● Kristen Stewart has been named the new face of Balenciaga's newest perfume because, as the house's head designer Nicolas Ghesquière says, "she shares the radical spirit of Balenciaga." By which he surely means to say, perma-pout or not, at least she's vampire-blooded and sparkle-skinned now. [E!]

● No-show Katy Perry and Harry Potter (and it's mostly absent stars), won big at last night's People's Choice Awards, raking up five and four wins respectively. [AP]

● Do things feel different this morning? It might be because the Bey-b is here! Beyoncé and Jay-Z welcomed a little girl named Blue Ivy into the world early Sunday morning in a New York Hospital. She is already very much loved. [NYDN]

This morning's denials were all for naught, as the two mega-celebrities announced their split this afternoon. "Sadly, Katy and I are ending our marriage," Russell Brand said in a statement. "I'll always adore her and I know we'll remain friends." They've only been married since October 2010, so it was a relatively short ride. Maybe time passes quicker and more annoyingly when you're a celebrity. It's not like they have any kids, anyways, so they can just get right back to doing it with other beautiful rich people.
