John Legend admits he had a history of cheating but says Chrissy Teigen changed his ways

John Legend has opened up about his past relationships, revealing that he had a history of cheating until he met Chrissy Teigen.

The Grammy-winning singer opened up during an interview on Armchair Expert with podcast co-hosts Dax Shepard and Monica Padman.

During the interview, Dax said: "I have a horrendous history of cheating. F**king deplorable... And there's all these great cheating songs on your albums, and I was like, 'I see another fisherman at sea,' ".

Dax then asked John if he too has cheated in his relationships.

John Legend, 41, replied: "Yes, I did have a history of [cheating]. Definitely in my 20's. I think what happened for me, you go through a lot of your life in your teens and I was younger than everybody in high school and college, and so I just didn't get a lot of girls. When I started to get that attention, I loved it.

"I escaped 'technically cheating' by keeping my relationship ill-defined. But it was really cheating. I definitely was dishonest and selfish... It was happening before I was famous."

The Oscar winner explained that as he entered the spotlight more, he got more "attention" and "took advantage of that, at that time."

However, things changed after he met Chrissy Teigen, whom he married in 2013.

"At a certain point, you just realize you're happier being honest. You're happier being faithful and being in love with one person," the 41-year-old said. "At a certain point, I just decided that person was Chrissy. I decided I wasn't gonna mess with somebody else anymore."

He said his "whole life" become "lighter" and it felt freeing for him to be honest.

John once said there were instant sparks when he first met Chrissy. In fact, they had so much chemistry that they had sex on the first night.

"We've talked about it before, but we had sex the first night and hit it off," John shared. "We were both seeing other people at the time. There was kind of a looseness at the very beginning, but we fell in love not long after that."

When asked by Dax if he ever feels pressured about his relationship, considering he and Chrissy are one of the most celebrated couples, John said: "I feel like it almost makes it less likely that I would do anything to f--k it up. Chrissy has 12 million Twitter followers. If I were to do anything, it would be career suicide," he explained. "It would be terrible. It just gives you another reason to not f**k it up."
