Ananova:

Filming for a TV advert was reportedly held up - because J-Lo's bum was too big for her skimpy outfit.

The singer failed to squeeze into her sexy black leather costume for the new £11m Pepsi commercial, reports the Daily Star.

Frantic staff had to stitch an extra piece of leather onto the outfit to cover the star's curvy bottom, according to the paper.

A set insider said: "It was quite comical, really. There were all these people ready to get on with the work when we realised there was a problem.

"Basically J-Lo's bum was just too curvy for the outfit."

Beyonce Knowles and David Beckham also feature in the mega-budget advert.
