Rita Ora was joined on stage by her 'X Factor' finalists Lauren Murray and Kiera Weathers at the KISS Haunted House Party in London on Thursday night (29.10.15).
The 'Body On Me' hitmaker performed in front of a crowd of zombies, vampires and witches at the sell-out fancy dress concert at the SSE Wembley Arena and brought out two of her three acts to sing harmonies with her during her energetic set.
Speaking after her performance, Rita revealed it was a "special" moment to sing with Lauren and Kiera - unfortunately third finalist Louisa Johnson could participate because she's on vocal rest
She said: "It was amazing, I just felt like I was at home. It's so crazy kind of filming a TV show and then kind of being on stage. I loved it and that's why I wanted to invite my two finalists. I have three but one of them is on vocal rest, but I wanted to kind of invite them out here to get a feeling of what it's like. They had a great time so it was a special moment."
Other performances at the gig came from Rudimental, Krept and Konan, Jess Glynne and Little Mix.
The girl group performed a trio of hits, including 'Salute!' and 'Love Me Like You', and were dressed as rockers KISS in black leather complete with the band's their trademark face paint.
The four girls - Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall - praised the fancy dress efforts of the crowd, shouting in unison, "Look at the Joker! Loving the pumpkin. Now we're going to teach you a little spell," before standing in formation to sing 'Black Magic'.
Jess captivated the crowd with a hairstyle of devil horns and a booming vocal performance of 'Hold My Hand' and 'Don't Be So Hard On Yourself'.
