Christina – aka Xtina – has explained that she resorted to using the mobility scooter to ensure she wouldn’t miss her daughter’s 9th birthday.

The Genie In A Bottle singer’s little girl Summer Rain wanted to mark her special day at the Californian theme park – and her mum was determined to be there.

Taking to Instagram, Christina has shared a video clip of herself speeding through Disneyland with Summer Rain on her lap.

Despite her painful knee, the Moulin Rogue star was all smiles as the lights twinkled behind them.

Christina was dressed all in black, with a baseball cap on her head in an attempt to help her blend in with the crowds.

She told her 9.1million followers: “A knee injury was not going to stop Momma from celebrating her favourite girl’s birthday at Disneyland!”

Insiders have told TMZ that Christina has decided to use the mobility scooter “to rest it to make sure it doesn’t get worse”.

Earlier in the day, the mum-of-two was seen being escorted around Disneyland by a private tour guide and was apparently given ‘front-of-the-line’ access to the rides.

She was spotted enjoying the Alice In Wonderland rollercoaster with her film producer fiancé Matthew Rutler.

The couple have been together for 10 years and are parents to Summer Rain.

Christina also has a 15-year-old son called Max Liron, who she shares with her ex-husband Jordan Bratman.
