Mario Lopez recently admitted he had a one night stand with a mystery "mega pop star," which sent the celebrity gossip world into a frenzy wondering who.
In his memoir Just Between Us, we learned that the 41-year-old Lopez lost his virginity at a very young age and had at least one very famous conquest.
During his recent appearance on the Ellen Show, he said the one-night sex romp may have taken place "six or seven years ago ... eight years ago?"
He wouldn't name names, but multiple sources now confirm what THG assumed from the start: Britney Spears was the "mega pop star" in question!
Spears and Lopez are friends, and were both single at the time of the hook-up, as Spears had parted ways with husband Kevin Federline in 2006.
Lopez was on a break with then-girlfriend Karina Smirnoff from 2006-08, during which Britney was not in the best place mentally and got around a lot.
