'I wish the whole thing hadn't happened. I like Cheryl,' said Lily, who once name-dropped the former Girl's Aloud star on her single Smile in 2006.
Not best pleased with the reference to her, Cheryl told Gordon Ramsay that Lily was 'a chick with a d***' and a war of words began.
Never one to go down without a fight, Lily posted an open letter to the Georgie star on her Myspace page stating: 'Cheryl, if you're reading this, I may not be as pretty as you but at least I write and SING my own songs without the aid of auto tune.'
She then called the singer a 'b**ch' who is 'stupid, superficial and as ugly outside as inside' amongst other hurtful comments over the years.
Lily is prone to getting herself in hot water with fellow celebrities, and recently seemed to make digs at Rihanna, Lady Gaga, Beyonce and Lorde in her single Sheezus.
Maybe time to stop making enemies, ey Lil?
