While Ashlee Simpson was showing off a picture of herself with Bronx Mowgli Wentz, daddy Pete Wentz was on Las Vegas one grind away from cheating with strippers.

On April 5th Pete partied with about 50 band members, dancers and pals, including Girls Next Door star Holly Madison, following a sold-out show at the Palms Casino Resort. A witness said:

"Everybody was going absolutely crazy. People were even drunkenly playing makeshift Slip ’n’ Slide with a mat and lubricant. Pete was in great spirits. He was dancing and singing along to his band’s own songs, grinding up against the dancers."

"At one point he was dancing on a pool table with the girls."

Earlier in the day, Ashlee, who headed back home after attending FOB’s April 4 concert in Irvine, California Tweated on Twitter: "I am beyond sad to leave my love… My heart is breaking as we drive home. I need my hubs."

Pete obviously wasn’t missing the Mrs.

Pete Wentz, best known for wearing guy liner, is trying to come up with more ways to get attention. This time he drank his own urine. It’s disgusting and weird, which is typical for Pete. He’s also a daddy, who isn’t setting much of an example for his child. Grow up Pete.

If you want to see the video you’ll have to search for it under Pete Wentz Plays Piss Roulette on YouTube.

If that’s acting, maybe we can start putting a lot of out of work people to work in Hollywood.

Here’s the pic of Bronx Mowgli Wentz. Who? It’s the Pete Wentz and Ashlee Simpson baby that no one cares about. People will care even less about Jessica Simpson’s baby.

Ashlee Simpson gave birth to a baby boy yesterday. His name is Bronx Mowgli Wentz (BMW). Pete Wentz is the dad. If anyone cares.
