Jon Gosselin's ex Hailey Glassman is celebrating her youth by throwing herself a 23rd-birthday bash at Quo nightclub in NYC on Feb. 19.

Hailey pokes fun at the age difference between her and Jon on her party invitation, titled "Black out or get out," which she sent to more than 3,000 people on Facebook.

"Come out and party for my 23rd. I may be turning 23, but I feel like 32. Come help me remember what it's like to be 23, aka young and fabulous again," she writes.

The newly single Hailey has just wrapped a photo shoot for Steppin' Out magazine and is all ready to party next week at Quo, which has hosted celebrities like Lindsay Lohan, Gwen Stefani, and Sean "Diddy" Combs. She assures her invitees that the "real Hailey" is back.
