Babies are popping out all over Hollywood this week! Congratulations to Nick and Vanessa Lachey on the birth of their son, Camden John. Victoria’s Secret Angel Adriana Lima and her former NBA baller husband, Marko Jaric, welcomed their second daughter, Sienna. Big sister Valentina is 2. And Levi Johnston has fathered a second child. In addition to the son he had with Bristol Palin, Levi now has a daughter with girlfriend, Sunny Oglesby. They named her Breeze Beretta. Yes, they named their little girl after a gun.

“The Newsroom” star Alison Pill “accidentally” tweeted a topless photo of herself — a picture intended for her fiance. But somehow, in her technological savviness, Alison tweeted — and then quickly deleted — her booby shot. She then tweeted this explanation: “Yep. That picture happened. Ugh. My tech issues have now reached new heights, apparently. How a deletion turned into a tweet…Apologies.” Um. Yeah. I’m always deleting stuff that ends up on Twitter.

Kris Jenner is furious that she’s in the middle of the “Today” backlash. She just wanted to talk about her boob job! She says it’s not her fault that NBC chose not to break away for a moment of silence to honor the 9/11 attacks. In fact, a source says she had no idea she was talking boobies when she should’ve been bowing her head. But while everybody’s criticizing NBC, Kris’ face is being splashed all over the place, so she’s guilty by association.

“Page Six” is reporting that Keith Urban has agreed to join “American Idol” and they’re just putting the finishing touches on his contract. A source says Nicki Minaj’s deal is “90 percent done.” The only sticking point is her endorsement deal with Pepsi. Sorta kinda a problem when Idol’s big sponsor is Coke. And finally, “Page Six” is reporting that Idol is probably just going to keep Randy Jackson on as the fourth judge. It’s just been too much trouble to get the other three slots filled.

Just like when she was on tour, Britney Spears’ handlers have laid down some ground rules for what goes on backstage. And the number one rule? NO ALCOHOL. According to UsMagazine.com, Britney’s reps sent out a notice: “Very important. We require you to empty minibars of all alcohol. And no gifts of wine or any other alcoholic beverages, please.” And if you can believe this…a source says Britney also banned pretty people from backstage. Seriously? The source says she doesn’t want to work with anybody “too pretty or stylish.”
