TWO Harefield Academy students spent a week teaching stars Ant and Dec how to jump, flip and tumble for a live TV performance.

The moves included splits, twists and balances, and a three-man tower with pupil Connor Bartlett at the base, holding Ant on his shoulders with a younger gymnast balancing on his head.

Connor and his twin brother Ryan are members of Spellbound, the gymnastics troupe that won the 2010 Britain's Got Talent contest.

For an edition of Ant and Dec's Saturday Night Takeaway on ITV, the brothers, aged 15, put in endless hours at Heathrow Gymnastics Club, teaching the pair their skills for the broadcast earlier this month.

Ryan said: “The hardest part of the experience was teaching Ant and Dec the moves.”

“It was a great laugh and Ant and Dec were hilarious.”

And Spelbound manager, Andy MacKenzie, revealed: “Dec had hurt himself in the rehearsals but managed to do the actual thing injured. That’s the perils of being a gymnast.”

The impressive four-minute routine – with the Geordie jokers in black and gold leotards – was choreographed by Kim Gavin, artistic director of the closing ceremony of the Olympic and Paralympic Games last summer.

The brothers got an added surprise when they bumped into Harry Potter star Daniel Radcliffe backstage.

Connor said “I thoroughly enjoyed the experience, especially meeting the celebrities that appeared on the show.”

Comedian Alan Carr appeared on the show, and afterwards tweeted: “Yes, I wanted to be part of the Spellbound performance but they couldn’t get hold of a winch at such short notice”

Both boys called the event an ‘amazing experience’ and said they would like to do it again sometime.
