Chrissy Teigen doesn't ''know s**t'' about music.

The 'Sports Illustrated' model, who's married to award-winning musician John Legend, has admitted she's not a huge fan of many of his biggest hits, but has conceded she's not got a great understanding of the art-form.

Asked which of the 'All of Me' hitmaker's songs were her favourite, she told DuJour magazine: ''It's easier to say what my least favourite John Legend song is, honestly. I remember when he was shooting the video for 'Green Light' and I was like, 'This is horrible. This isn't gonna go anywhere. I hate this song so much.' There was nothing about it I liked.

''And then all of a sudden it's all over the radio. It was his first big radio hit. And I was like, 'Listen kid, this song's going nowhere.' Clearly I don't know s**t. So now I don't really speak up as much.''

Earlier this month, John said his wife is ''more brazen'' on social media.

John explained: ''When Twitter first started, I was worried. Like, don't be too honest, don't share too much.

''But, then, I think she's actually more brazen on Twitter than she is just in regular life. She shows more of her sweet side in regular life.''
