The rapper will be debuting his new single which the mother-of-one introduced to him to and is also featured on.

Christina teased: 'If you've got a record called Start A Fire, you can just imagine the pyro, there's going to be a huge moment I just have to worry about not tripping.

'I think with the two of us on that stage, there will be fireworks and it will be awesome. We have to really start a fire,' she added.
