It's a ridiculously trendy film featuring the likes of super-cool Britain's Got Talent acts Flawless and Diversity.

So when Heather Mills got an invite to the premiere of StreetDance, it seems she was intent on trying to be as hip and cool as possible for her red carpet arrival.

The ex of Sir Paul McCartney turned heads as she squeezed into an extremely short - not to say tight - playsuit, complete with thigh-high legging-style boots.

But it would be fair to say that her bid for a youthful look turned into something of a fashion disaster for the 42-year-old charity campaigner.

Strutting down the red carpet at London's Leicester square in the ensemble, Heather was in customary attention-grabbing form as she pouted and played up to the cameras.

No doubt amputee Heather, who has a prosthetic left leg, would have spent a good deal of time ensuring her outfit was pinned and fastened in all the right places.

StreetDance features last years Britain's Got Talent winners Diversity, as well as rival dance troupe Flawless.

Fellow BGT winner George Sampson also takes a bow in the 3D movie, alongside Charlotte Rampling, Rachel McDowall, Nichola Burley and Frank Harper.

In the film, sparks fly as the worlds of street-dance and ballet collide.
