Chrissy Teigen and John Legend got into their "biggest fight ever" row at Kim Kardashian West and Kanye West's wedding.
The 'Lip Sync Battle' star - who has children Luna, two, and Miles, seven months, with her spouse - admitted she wants to apologise to the couple every time she sees them because of the tension she caused at their 2014 nuptials in Italy.
Asked about the row by a caller on 'Watch What Happens Live with Andy Cohen', John said: "I don't even remember what it was about."
Chrissy added: "We try to think about this all the time. It was a major blow-out to the point where every time I see them I feel like apologising for it."
While John, 40, thought the pair had managed to keep the bad feeling hidden from the bride and groom, his wife disagreed.
