X-factor mentor Kelly Rowland just came back in London to rehearse for this week’s episode.

The singer went to Fountain Studios wearing an eccentric head-gear and oversized earrings.

Misa B and Janet Devlin, her remaining acts on the show looked tired and weary.

While fellow co-host, Tulisa Contostavlos has also been rumored to be ‘crackin up’ after her bitter war with Kelly Rowland two weeks ago.

She failed to make an appearance on some commitments like radio shows and TV interviews.

Her publicist, Simon Jones told TheDailyMail that, “Tulisa has been unwell this week and so I made a decision, as her publicist, to cancel a few of her promotional publicist on her behalf.”

He added, “But she is feeling a lot better after some rest and is ready for tonight’s show. Tulisa’s number one priority is  her two groups and we wanted to make sure all her time was focused on mentoring them and giving them 100%. She is really excited about tonight’s show theme.”

“She’s also looking forward to catching up with Kelly Rowland today.There are some ‘untrue’  stories being written about her “snubbing” Kelly, when the reality is everything is cool between them and now after they talked about everything through last Sunday.

Meanwhile, this week on the show, Gary Barlow and Louis Walsh was the ones who are at war.

The performer was Frankie Cocozza who sang the Black Eyed Pea’s “I Got A Feeling” on which Barlow said that it his performance feels really bad karaoke.

Walsh did not like Barlow’s comments and said, “Frankie we are half way through the competition and it’s all getting serious..that was really bad karaoke and I don’t know how you’re still here.”

He added, “You are not a rock star, you’ll never be a rock star and the only big thing about you is your hair.”

Tulisa, who stayed away from the harsh word war said, “Frankie, I was just actually starting to get comfortable with the edgy rebellious Frankie but song choice wise, it was a bit too soft for you. It did not work for me tonight, it was not edgy enough for you”

Kelly Rowland also told her take on Frankie saying, “First of all, Louis I think that you are out of line telling someone what they will never be…”

Walsh then talked back and said, “At least I’m here every week.”

Rowland fired back and said, “OK.. cute, for somone to say you’ll never anything is really mean.. I’m sorry!”

Louis then told Kelly, “Atleast I’m honest. I’m not playing with the cameras like you.”

Barlow, who tried to focus back to Frankie said, “Back in your cage, Louis, back in your cage.”

“I completely got the wrong song for you, I apologize for that right away. You came out and you did bring it tonight and I know your under great pressure and I do feel sorry for you.To be booed on this stage is disgusting. That should not be allowed. You did your best tonight.”

Walsh interjected saying, “Oh shut up Gary, just shut up how can you justify that? All you have to do is sing in tune?”

Barlow told him, “I won’t shut up, how would you know?”

Kitty Brucknell was also not saved by the judges criticisms.

Kelly told her that her performance of Madonna’s Like a Prayer was a little flat. Barlow also told her, “I have never really seen you around before but you can’t dance babe! I know that sounds rich coming from me, but it looked a little clumsy.”

Walsh then fired back about Kitty saying, “Kitty is really in a bad way backstage, she’s crying, she’s hysterical and it’s not fair. She’s in a real bad way because of the comments.”

While everyone is fighting, Tulisa said at the start of the show said, “Everyone is happy. We’re good. It’s all about the contestants.”

She then, high-fived with Kelly to prove they are okay.
