In an interview with Ellen DeGeneres, Mario Lopez admitted to having a one-night stand with a “mega pop star” which has been identified as Britney Spears.

Lopez, now 41, says the one-night stand happened several years ago in Las Vegas.  “I’m trying not to give too much away without giving too much away,” Lopez told Ellen.  He claims the affair could have been anywhere between six and eight years ago.

Regardless of the year, if six and eight years ago is an accurate estimation, both Lopez and Spears were single.  Spears split from her husband Kevin Federline in 2006 and Lopez was on a break from his girlfriend at the time, Karina Smirnoff.  Previous to that relationship, Lopez was in a relationship and married to Ali Landry.  Their marriage lasted only two weeks, as Landry split from Lopez after citing that he was “too friendly” with a female guest at a party the two attended.

Continuing the interview, Lopez claimed that he and Spears were still friendly.  Lopez even starred recently in Spears’ Vegas show, Piece of Me.  Spears, 32, has a residency in Vegas with her show.

The tryst with Spears is one of many stories Mario Lopez details in his tell-all memoir.  Lopez claims his drug of choice is sex, and  Lopez said he “lost his virginity one day before his 13th birthday, and fathered a child when he was 15, but the mother ultimately chose to terminate.”

Mario Lopez is currently a co-host on the entertainment news program, Extra!.  Britney Spears has yet to comment about the alleged affair.
