They gonna party like it's his birthday because it IS his birthday!
Their son Bronx's birthday! The little guy turned 5 years old!!!
It seemed like everyone was there including Pete, Ashlee, and Bronx plus Ashlee's sister Jessica Simpson and Ashlee's boyfriend Evan Ross along with his mother Diana Ross! Pete's girlfriend Meagan Camper was there as well (pictured above)!
And who could forget Jessica's precious daughter Maxwell along with her adorable bro Ace and his daddy Eric Johnson!
Pete seemed a bit wary about the whole thing, but his girlfriend didn't look like she had a care in the world! Talk about not letting the awkwardness affect ya!
As for Bronx - he seemed like he couldn't wait to get his party on that Saturday at The Coop in Studio City. He even rocked a beautiful KISS shirt!
All hail the adorableness!!!
