John Legend allegedly cheated on his fiancée Chrissy Teigen in a nightclub last week.
The American singer became engaged to model Chrissy Teigen after dating for four years in December 2011. He recently spoke at length about his wedding plans, but it has been suggested the pair could be going through a rocky patch.
According to New York Post, the 34-year-old star was seen in a passionate embrace with another woman during a night out.
John and his friends partied at Manhattan hotspot Acme on Friday, where the group began talking to two attractive young women. One of the females had dark hair and the other was fair, with the pair spending the whole evening with the singer's group.
The publication claims that the blonde woman went to the bathroom at around 1am, with John immediately following her.
"He was walking in, and just grabbed her arm and brought her with him,” an insider alleged.
Another source saw the same thing and claims to have heard the mystery woman telling her pal she and John had enjoyed "a steamy make-out session".
"They were in there a couple minutes," a separate insider said, adding soon after the woman spotted another guy she liked the look of and began chatting to him.
Neither John nor Chrissy's representatives have commented on the report.
Earlier this week John revealed he has written a song for his wedding.
"It's going to be good music, good food and a good time," he said of the big day. "There's a song on my album that actually could be pretty good for the wedding. It's called All of Me and it's inspired by Chrissy. She loved the song and cried when she heard it."
In February, Chrissy claimed she and John would be married by the end of the year after having to postpone their nuptials several times. She hinted she would like to tie the knot in spring or summer.
This week, the 27-year-old model used Twitter to blast other women for hitting on John.
"I honestly think so many more of us would get along if you didn’t want to [bleep] my fiancé," she wrote.
