Louis gets the claws out...big surprise.
Luckily, little Louis was quick to clarify that the comment was meant as a joke - well, sort of.
Speaking at the X Factor launch yesterday, he said: "That was a joke, come on… well she is a little bit - in a good way.
"We always have fun. I call her a chav in a tracksuit, but it’s fun. She’s young and she’s new and she’s had one hit. That’s fine."
As 'fun' as it may be Louis, we can't help thinking that one of these days, you're going to get a smack in the mouth. Or at the very least a clip round the ear.
"We’re really good friends but I like to tell it like it is," Louis continued. "When I was selling records with Westlife they were really selling records.
"They’d sold 44 million, they sold out arenas… Are N-Dubz ever gonna do that? I don’t think so."
To be fair, he's sort of got a point there. So, what does Tulisa think of Louis' comments? She claims he's just trying to get a reaction out of her.
"The only reason why Louis does that is to wind me up, he knows exactly what he’s doing." she said.
Phew, so it appears noone is going to start hurling glasses of water/insults around just yet then. They're probably saving that for the live shows.
What do you think about Louis' comments?
