First it was Lily Allen, now Lady Sovereign has had a rant about Corinne Bailey Rae.
The pair had to be kept apart after Lady Sov, 21, laid into Corinne backstage at a recording for T4.
Sovereign, 21, told the 3am Girls:
"I told her she was boring and that she should be called Corinne "Boring" Rae. I think she's a fake. She's too nice. She sings about life being as sweet as roses but it's not. It's crap."
Corrine failed to take the bait and get into an argument.
Lady Sov continued, "Corinne just said 'whatever' and turned on her heels like she was The Queen."
