Wedding Bells for Hef?

According to Hef's second girlfriend Bridget Marquart, 34, next season of The Girls Next Door features a "huge wedding."  So of course we have to ask, could Hugh Hefner, 82, finally be tying the knot with main girlfriend Holly Madison, 28?

Bridget was reportedly overheard dishing about the show, hinting that she and fellow girlfriend Kendra Wilkinson, 23, will be moving out of the Playboy Mansion once season five wraps.

"She said they will be moving on since Holly is Hef's main girlfriend," a source tells OK!.  Holly is also getting more involved with the magazine.  "Holly is taking a bigger role in the company, directing pictorials," the source added.

For the twice married Hef, let's hope third time's the charm!
