There's a Jednado in London today as Jedward promote their upcoming new film Sharknado 3: Oh Hell No with a giant rubber shark - see the lads in action here!

Brothers John and Edward are making their big screen debut in the third outing of the Sharknado series of shark-based terror satire, which will air on the Syfy channel on July 23 at 10pm.

The lads have also contributed to the film's soundtrack with their latest single Oh Hell No becoming the film's theme song.

The film also stars Tara Reid, who befriended the twins in 2011 while appearing on Big Brother together, Frankie Muniz, David Hasselhoff and Kelly Osbourne, and the plot centres around a monstrous tornado of ravenous sharks travelling from Washington, DC to Orlando, Florida. Obviously!

Jedward have tweeted a number of videos from London this morning:
