The 30-year-old model has admitted her and the 'All of Me' hitmaker had the worst argument the pair have "ever" had during the 'Keeping Up With the Kardashians' star's wedding to rapper husband Kanye West in May 2014, because of drinking alcohol.

Speaking to Kim about their lovers tiff on her website kimkardashianwest.com, the mother of one - who has three-month-old daughter Luna with the singer songwriter - said: "John [Legend] and I got in the biggest fight at Kim and Kanye's wedding that you've ever seen in your whole life ... [it] came from alcohol."

And the 'Selfish' author has revealed the exact same happened to her and Kanye at Chrissy's marital ceremony in Italy in 2013.

The television personality explained: "Wait, I got in a fight with Kanye during your wedding. I didn't go ... [North] was just born and I was so fat, and I had nothing to wear, so then he kept texting me, 'Babe, this is the most beautiful wedding,' 'Babe, this is so pretty. I really wish you were here at Lake Como.' ... Literally a play-by-play text. We got into the biggest fight. 'Just stop texting me. Go enjoy the wedding, you're making me feel so bad!'"

Meanwhile the 'Lip Sync Battle' co-host - who features in Fergie's latest 'M.I.L.F.$' music video alongside Kim - has revealed she felt "nervous" to meet Kim, and felt like a "weirdo" because she already knew everything about the reality star.

She explained: "I remember this because I was so nervous to meet you. I don't know, I'd been watching. I knew all about you. I felt like kind of a weirdo.

"You made me feel so much better because we went to the bathroom and you had me zip you up. I was like, 'Oh my gosh. She has Spanx on. She's cool. She's normal.' Yeah, I remember that pretty well for some reason.'"

However, the pair believe motherhood has mad either friendship even stronger.

The mother of two - who has three-year-old daughter North and seven-month-old son Saint - said: "I think we've gotten closer since we've been moms. Because when you're a mom and you've figured it out, you want to tell all your friends going through the same experience."
