Uh oh, not again! Blonde Electra's Jazzy King leans in to kiss nipple-baring sister Ruby in her sheer floor-length dress

Blonde Electra sisters Jazzy, 24 and Ruby, 22, caused a scandal when they shared a passionate kiss at the X Factor final on Sunday.

But it looked like the outrageous pair were at it again on Thursday night when they put on a flirtatious display for the cameras in some characteristically wacky ensembles.

The duo, who called themselves 'single Pringles' in their competition audition, only had eyes for each other when they attended the Wicked musical theatre press night in London.
