The criticism was sparked by Lily Allen, but Sovereign apparently told Bailey Rae what she thought of her in person.
She told Entertainmentwise that during a recording for T4 she met the pop singer and told her that "she should be called Corinne 'Boring' Rae."
She went on: "Corinne just said 'Whatever' and turned on her heels like she was the Queen. I think she's fake. She's too nice. She sings about life being as sweet as roses. But it's not, it's crap."
But Bailey Rae has retaliated saying that she pays no attention to such comments. She said: "After meeting big stars like Mary J. Blige and hearing they love my music I don't really care what they think."
