The R.I.P. hitmaker attended the movie extravaganza in the South of France in May (15) and she was snapped heading to a concert in a white suit/gown with her hands over her chest, apparently attempting to preserve her modesty.

Now she has revealed she was desperately trying to hold the ill-fitting frock together after it "exploded" under the strain.

Ora tells Q magazine, "I was wearing an outfit which didn't fit properly so I just sort of forced myself into it and then it all exploded. The zip broke, the trouser slipped... Pretty embarrassing."
