"Without Ashlee around, he’s back to focusing on his own projects and finally letting loose. This is his coming out party — and he wants everyone to see he’s better than ever," an insider says.
Just this past Thursday night he was spotted at Lucky Strike Lanes behind the turntables as the night's DJ and even rocked out throughout the night, lifting his shirt to show off his abs.
You just do you, Pete. Just make sure you're new bachelor lifestyle isn't getting in the way of quality time with your little boo, Bronx!
