He got a piece of this pop star! After Mario Lopez revealed in his memoir Just Between Us that he had a one-night stand with an unnamed "mega pop star," multiple sources confirm to Us Weekly that the celebrity was none other than Britney Spears.
According to Lopez, 41, the rendezvous occurred many years ago in Las Vegas. "I'm trying not to give too much away without giving too much away," the scribe told Ellen DeGeneres on Oct. 2. "It was maybe six or seven years ago… eight years ago?"
At the time of their hookup, both Spears and Lopez were single. The pop princess, 32, split from husband Kevin Federline in 2006, while Lopez was on a break with then-girlfriend Karina Smirnoff from 2006 to 2008. The '90s teen heartthrob was several years out from his brief and failed marriage to model Ali Landry.
The Extra host also told DeGeneres that he and the newly revealed mystery lady still remain "friendly." In December 2013, Lopez joined Spears onstage for the opening night of her Vegas residency, Britney: Piece of Me.
Along with his steamy one-night stand confession, the Saved by the Bell alum also revealed other juicy tidbits about his love life in his memoir.
His fling Spears, meanwhile, and David Lucado called it quits this past August. The "Perfume" singer later told concertgoers at a Vegas show that he had been unfaithful.
