Pete Wentz isn’t letting his divorce from Ashlee Simpson damper his spirits. If anything, he’s embracing his new-found freedom. While in New York with his band The Black Cards, the former Fallout Boy has been embracing his bachelor lifestyle — partying into the wee hours of the morning at various hotspots around the city.

“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,” a source told Celebuzz.

On Thursday evening, his band took the stage at PUMA’s bowling shoe launch at Lucky Strike Lanes. Pete manned the DJ turntables, rocking out and lifting his shirt a few times to show off his abs as singer Bebe Rexha belted their electro-pop hits. The previous night, Pete was spotted at SVEDKA Vodka’s National Walk Of Shame party, hanging with the likes of Denise Richards and Rob Kardashian.

Although Pete is very publicly enjoying his time away from home, don’t expect him to be as open about his love life, the source added.

“Although Ashlee made a public photo-op with her new man, don’t expect Pete to do the same. He’s going to lay low and is embracing his singledom,” the source said.

Pete’s ex, who filed for divorce in February, recently made headlines when she went public with her new beau, Boardwalk Empire star Vincent Piazza. The pair were spotted sharing a sweet summer kiss in New York City.
