LAS VEGAS—No record exists to back claims by former ‘N Sync member Lance Bass that he once married a girlfriend in Las Vegas, according to a clerk at the Clark County marriage license bureau.

Bass, who is openly gay, told E! News in an article published Oct. 30 on its website that he got hitched in “1999 or 2000” and the bride was “just a friend.”

A search of records from 1974 to 2007, however, indicated no marriage license under his name was pulled in Clark County, which encompasses Las Vegas.

Bass, who has been promoting his new memoir, “Out of Sync,” announced in July 2006 that he is gay. He has said that he didn’t reveal this earlier because he didn’t want to affect ‘N Sync’s popularity.
