Now they've turned their attentions on Victoria Wood-wannabe Lucy, dismissing her as moody and in desperate need of a smile transplant.
'A smile wouldn't go amiss, if you know what I'm saying' Charlie told Radio 1Xtra
In an interview with Radio 1Xtra, rapper Simeon said: "Lucy Spraggan had so many bad days and it was hard to try to connect and talk to her."
Charlie added: "She sounded a bit grumpy. Don't get me wrong, she's talented. But a smile wouldn't go amiss, if you know what I'm saying."
Simeon also took a swipe at Scouse powerhouse Chris Maloney, growling: "Chris had a tendency of being a little diva, but he's a cool guy."

After they were thrown off the show, the pair took aim at Gary and Nicole for chinwagging during their sing-off performance.
Charlie told The Sun: "They were whispering to each other and I thought, 'I'm trying to sing for my place and they were chatting.' That's just rude."
Nice to see they aren't bitter or anything.
