With his imminent wedding to Ashlee Simpson, Fall Out Boy bassist Pete Wentz hit the town for his bachelor party.
The big night was shared with soon to be father-in-law Joe Simpson, his band mate Joel Madden and quite a few other male friends. They started their evening doing dinner at Mr. Chow.

The rocker seemed pleased to be getting married. He must not mind his father-in-law hanging around all the time, which is a good thing. Soon to be sister-in-law Jessica Simpson has not been as lucky with her men and their interaction with her needy father. Jessica and boyfriend Tony Romo are allegedly on the skids.

As the group left Mr. Chow on to their next destination Joe was seen patting Pete on the back and saying “this is the man.” We wonder if he meant…yeah, this is the man who is going to take Ashlee off my hands so I can spend more time helping Jessica find a new boyfriend.

Hollywood Roosevelt Hotel was the last place with a guy party in the Marilyn Monroe Suite overlooking the Tropicana Bar and Roosevelt pool. This is where it gets a little strange. Jessica was apparently in the hotel lounge with a couple of her friends. Coincidence?

The bride-to-be held her party at Kiki De Montparnasse which is known for its luxury lingerie and intimacy products. Perhaps her party was held there because she’s PREGNANT and can’t drink?
