Chrissy Teigen is not averse to sharing details about her private life with the public, so it should come as no surprise she’s opened up about something deeply personal.

Chrissy and husband John Legend revealed the biggest, worst fight they’ve ever had when they appeared on Watch What Happens Live with Andy Cohen this week.

As the couple explained, it went down at Kim Kardashian and Kanye West’s 2014 wedding in Italy, of all places.

“It was a major blow out to the point where every time I see [Kim and Kanye] I feel like apologising for it,” Chrissy said.

“I think I was really intimidated and I just think it came from a lot of insecurity and I just took it out on John,” she added.

“It was just a lot of fabulous, amazing people in one room.”

She added that she was drinking, which sometimes means small arguments can turn into bigger fights.
