Britney surprised superfan James Colbourn for tea at the Savoy hotel during her stay in London back in October for ITV’s “Surprise Surprise!”

The show’s host, Holly Willoughby, arranged for Britney to meet James after his sister Sadie nominated him for his unfailing support since she gave birth to twins George and Riley at just 26 weeks.

The babies developed cerebral palsy and James has supported her “every step of the way,” his sister wrote.

“He gave up his spare time and cared for the boys as if they were his own – I could not have done it without him,” she tells the show.

The Christmas special, which also stars Olly Murs, shows James gasp with excitement as he spots Britney pretending to be a waitress tip-toeing towards them.

Britney recently tweeted her dismay at missing favorite soap “Coronation Street” when in London promoting “Work *****.”

A source said: “Britney has been coming to the UK for years and loves all things British. Production staff were stunned when she admitted she actually used to watch the show – and loved Cilla.

The source added: “James is a massive Britney fan. He nearly faints when he spots Britney because he thinks the surprise is having afternoon tea at The Savoy and then Britney walks in with a tray of scones and he can’t believe it.

“It was a lovely surprise, even if it was a little overwhelming for James.”

The episode airs December 18 at 8pm on ITV.
