Rita Ora is red hot at the X Factor

Rita Ora looked incredible on Saturday night wearing a bright red jumpsuit. The Hot Right Now singer took the plunge in the daring outfit whilst she cheered on her two remaining acts Louisa Johnson and Lauren Murray.

The 25-year-old who often favours glamourous evening gowns changed it up a bit in the statement piece that featured a sequinned design and a large red cape. Keeping the rest of her look simple, she chose to wear a pair of plain black strappy heels and styled her blonde locks into a side parting.

Fellow judge Cheryl Fernandez-Versini also shunned a dress opting for a smart black and grey jumpsuit. She too chose to keep her hair wavy and make up simple with just a flash of red lipstick.

It was a disappointing night for Rita’s act Louisa who failed to impress Simon Cowell with her rendition of Justin Bieber new song Love Yourself. Concerned about the young singer the media mogul asked "Is everything OK? You didn’t seem comfortable. You also didn’t seem to pace the song properly. It was not your best performance."

Jumping to the defense of her mentee, Rita said: "Excuse me, but when you’re singing an acoustic song on live TV it’s the voice that leads the guitar. You did a wonderful job." Feeling like she had to explain herself Louisa responded, "I’m not very well, I’m sorry."

Ché was very upset about forgetting the words to Adele's song Hello

Nick Grimshaw’s contestant Ché Chesterman also had a difficult night. The singer, who favours big ballads, forgot the words to Adele’s latest hit song Hello. Simon, once again, was the first to comment on the 19-year-olds performance telling him: "You’ve lost your way and you’ve lost your confidence. At this point in the competition, you’ve got to develop your own style…you look like you’ve just come from work."

Feeling like he let his supporters down Ché tweeted an apology saying : "I ruined it…I’m so sorry guys, I truly am!"
