The newly wed Peter Lewis Kingston Wentz III celebrated his 29th birthday in style last night at a semi-private birthday party that was held in the VIP area of the Foxtail nightclub that was thrown in his honor by famed LA partyplanner Brent Bolthouse. Pete and his new wife Ashlee Simpson have announced that the couple are pregs with their first child … but that didn’t keep Ash away from the festivities. Here are pics of the happy couple as they made their way into Pete‘s party last night:

So to ring in Pete’s last year before turning 30 — and maybe his last big party before he has to start changing diapers — nightlife maven Brent Bolthouse arranged for a private party for the couple in the exclusive upstairs VIP area at his hot Hollywood club Foxtail, where the newlyweds — Pete in an all-black tuxedo-ish getup, Ashlee in a sleeveless ruffled dress and ankle boots — arrived around 9:45pm in a stretch limo. Even though there was Secret-Service-style security on-hand, with bouncers laser-scanning VIP wristbands and extra muscle men circulating around the club, that didn’t stop the mom-and-pop-to-be from spending most of the party downstairs, away from their invite-only guests upstairs. “Pete and Ash worked the dining room,” one clubgoer tells OK!. “They were walking from table to table, chatting and shaking hands.” Maybe Pete is making a bid for the Vice Presidency? Pete and his still-blushing bride eventually settled at a long table with eight friends who were eating and drinking the night away. “They didn’t sip a drop of alcohol,” one insider says about Pete and Ashlee. “Though I can’t say the same for their guests!” At the stroke of midnight, waiters brought out a birthday cake, with “Happy 29th Birthday Pete” written on it, to the table while the crowd sang “Happy Birthday.” The pop-punker had a bit of trouble when he attempted to blow out his candles, requiring three attempts and accidentally dowsing the front of his suit jacket with icing. Around 1am, it was time for the couple to call it a night, as they exited out the front door and into their awaiting limo, which took them back home.What a sweet and pretty picture. I love the clarification that neither Pete nor Ashlee touched any of the free-flowing booze that was readily available at last night’s party … they surely don’t want anyone forgetting that Ashlee is pregs. No word on whether or not Pete‘s new BFF John Mayer was in the hiz last night but I’m sure that good ol’ Petey wasn’t wanting for friendly companionship at his party. Happy Birthday, Pete … sounds like you had a very lovely time last night. [Source]

Despite the fact that Pete Wentz just got married to Ashlee Simpson and John Mayer has been lurvin’ all up on Jennifer Aniston lately, the guys have been spending quite a lot of time together. This new friendly relationship got started in the blogosphere … first Pete blogged about his love for John and then John blogged about his love for Pete — and the rest is history. Here are a few pics of Pete arriving at John‘s place here in SoCal this week for, what appears to be, a little jam session/playdate:

Photo credit: Bauer-GriffinIn all honesty, I’d be very interesting in hearing what these two have got going on in these jam sessions. It’s entirely possible that we may never get to hear what a new original collabo between these guys might sound like but something tells me that they might be up for releasing any new tunes they concoct together (much like their just released MJ collabo). I’m also interested in knowing if they prefer playing GI Joes or Transformers. [Source]
