Christina – who has son Max with first husband Jordan Bratman and Summer with Matthew – wrapped her hugely-successful Liberation tour last November, and the experience of getting back on the road inspired her new residency.

She added: ‘Liberation was such a success for me. The last time I had been on tour was when I was pregnant with my son [2007’s Back to Basics].

‘And being such a mama bear and wanting to take care of my kids and all of that first it was a long time coming.’
