As Mario Lopez is days away from turning 41 years-old, he has decided to take a step back and reflect on his success and achievements in the form of a memoir. The 'Saved by the Bell' alum has already generated a lot of buzz surrounding the book by revealing it contains some rather juicy details.

Lopez's upcoming memoir is very candid about his personal life

On Thursday (Oct 2nd), Lopez stopped by the Ellen DeGeneres Show to discuss his memoir 'Just Between Us,' and spoke very candidly on an array of events in his life including having a one-night stand with a familiar face.

During the interview, the host Ellen quickly probed the hunky actor to shed some light on a sexual encounter he recalls in the book. "You also admit that you had a one-night stand with a major pop star," she said.

"Well, yeah," he replied. "I'm trying not to give too much away without giving too much away. it was maybe six or seven years ago. eight years ago?"

After Lopez admitted their still "friendly," Ellen asked if he had interviewed her since the deed took place.

"Oh my gosh, I can't, I can't," he said. "You know, my wife, who is the most important as far as her opinion to get her blessing and she's totally cool and she's knows everything, but out of respect for her and out of respect for this person, you know, I'm a gentleman and I don't want to drop names."
