Bachelor Party!

With his impending nuptials taking place this weekend, Pete seemingly had a pretty tame bachelor party last night at Mr. Chow.

Tame, because two of the participants were his father and his soon-to-be father-in-law, Joe Simpson!

Or maybe it was tame because Pete's expecting a little Fall Out Boy, and Joe wanted to keep an eye on his daughter's babydaddy to make sure he didn't do anything too crazy!

But everyone seemed to be in a great mood, with the groom and the father-of-the-bride joking with the paps.

Apparently, the boys met up with the Bachelorette party (which looked a bit wilder) later that night at Teddy's - stay tuned for that story coming soon!
