Kanye West turned heads last month when he dissed his good friend Jay-Z's collaboration with Justin Timberlake; and it seems Timberlake has cheekily hit back.
West was performing in London in mid-February when he made it clear he was not a fan of global hit Suit and Tie.
"I got love for Hov, but I ain’t f***ing with that Suit and Tie," he said.
And, presenting Saturday Night Live last night, Justin appeared to hit back.

Whilst performing the track with Jay-Z, he changed the line "S**t so sick, got a hit and picked up a habit" to "My hit's so sick, got rappers acting dramatic".
With Jay-Z and Kanye being so close, we doubt it was anything more than playful banter - but do you think Kanye will fire back?
Justin's stint on Saturday Night Live seemed to go very well. It was his fifth time as host, leading to cameos from fellow 'Five Timer's Club' members Alec Baldwin and Tom Hanks.
He was spotted with Jessica Biel after the show heading to an afterparty.
