Saturday gossip round up is here! Charlie Sheen's show takes a dive after some promising developments. Nicole Richie is sick of your pregnancy rumors. Gucci Mane is arrested for throwing a woman out of a car. Let's go.

  • Charlie Sheen's live show, I Need Cash to Pay the Mortgage on My Mansion, continues to stumble through the U.S. After getting a standing ovation at his show in Cleveland led some to believe Sheen had turned a corner. Not true: He bombed again at Radio City Music Hall last night. Says New York Post columnist Andrea Peyser: "For an hour, Sheen chain-smoked like a criminal — "can I have a f—king cigarette?" — lobbed the F-bomb like a 4-year-old suffering from Tourette's, and praised Donald Trump as a "real f—king dude." He ended his performance early and ran off the stage, into the protective bosoms of his goddesses. Anyone see anything? [NYPost]
  • But Lindsay Lohan thinks Charlie Sheen is the bee's knees and a very funny person. Trainwrecks fly together. [People]
  • Nicole Richie is not having another baby, you guys. Pregnancy rumors have been flying after she was seen sporting a stomach that was not so skinny as to be concave. But she's not pregnant! She tells People: "Contrary to recent speculation, I am not pregnant. This irresponsible reporting continues to feed an atmosphere of self-doubt and insecurity. To publicly point out a change in anyone's body is mean-spirited and cruel. People's bodies change and change again. This is not newsworthy and is a waste of valuable media space that should be used for more important issues." Yeah, let's focus on more important issues. Like, we hear Leann Rimes is really thin now? [People]
  • Rapper Gucci Mane, he of the ice cream cone face tattoo, was arrested in Atlanta yesterday for allegedly pushing a woman out of a car in January. He can be happy that he didn't get pepper sprayed like last time. [TMZ]
  • TMZ has a picture of Tiger Woods—currently doing very well at the Masters—playing craps at The Atlantis resort in the Bahamas. Woah! Tiger Woods is doing something entirely legal which has a very slight social stigma! Oh, how the standards for a Tiger Woods scandal have fallen. [TMZ]
  • Kristen Stewart turns 21 today. Finally, she'll be able to be mobbed by fans and paparazzi while drinking in a bar. [E!]
  • Jim Carrey is sporting a totally zany mohawk. It's almost as crazy as that time he dated Jenny McCarthy for three years. [E!]
  • Hey, there's a new Kendra Wilkinson sex tape. We shall call it: Kendra Exposed 2: Bigger, Badder, More Lesbian. [Popeater]
