Other Women unite!

Michelle "Bombshell" McGee has just landed a new gig: refereeing a boxing match between porn star Gina Lynn...and Hailey Glassman, Jon Gosselin's ex.

Celebrity Boxing Federation promoter Damon Feldman confirms to the New York Post that Jesse James' alleged mistress will ref a May 7 bout between Glassman, 23, and X-rated actress Lynn at Philadelphia's Polaris Club.

Glassman and reality dad Gosselin, 33, parted ways bitterly last December. He accused her of vandalizing his Manhattan apartment; she sniped to Steppin Out magazine that her ex was "hung like a nine-year-old boy."

McGee, 32, was the first woman to blab to a tabloid about her reported 11-month affair with Sandra Bullock's husband James, 40. On Friday, the tattooed mother of two returned to work at Pure Platinum strip club in San Diego, Calif., where she performs topless and charges $100 for private lap dances.

The alleged mistress has changed her stage name from "Avery" (also her five-year-old son's name) to "Bombshell," and told Radaronline Friday that she "has a lot of exciting things coming up in my life."
