Angel will be seen causing controversy on tonight’s X Factor episode.

The girl group try to impress the judges with their rendition of Willow Smith’s Whip My Hair Back and Forth, but when Tulisa Contostavlos admits that she didn’t love the performance, they hit out, implying that she has no singing talent.

After their audition, the N-Dubz singer said:

Ok girls, I’m just going to put it as blunt as possible to you, I think all the energy and all the dance moves is to cover up the fact none of you can really sing.

Vanessa from Angel hit back saying:

Umm, it’s a bit rich coming from you but…

Kelly Rowland then chimed in to defend her fellow judge, ranting:

“Can I just say one thing, coming from a female group that always talks about how women should come together and they shouldn’t be bitchy towards one another, I understand that you have an opinion, but at the same time, you came here for us to judge you and there was no reason for you to come back at her like that, and I can tell that these two don’t appreciate the fact that you did that, because what if you just messed up their chances for an opportunity, they are the group!”

After they failed to win a place in bootcamp, Vanessa just couldn’t keep quiet about her hatred of Tulisa and went on to blast:

Unhappy times. I think that was her being bitchy, I was just doing the same back its just one of those things, that’s how I am, but I was about ready to punch her in the face if I’m perfectly honest.

So who’s side do you take? Can Tulisa sing? Leave your comments below.
