Blonde Electra Kiss During ‘X Factor' Final (And Yes, They're Sisters) (VIDEO, PIC)

The ‘X Factor’ final had barely got underway on Sunday night when the nation’s collective jaws dropped after witnessing sisters Blonde Electra locking lips for a kiss on stage.

Yes, sisters. Kissing. On the lips. On the ‘X Factor’ final.

Blonde Electra do their best Britney/Madonna impression. Except Britney and Madonna aren't related

The duo, who were the first act to leave the competition after being voted off in the first week of live shows, were on stage with the rest of the ‘X Factor’ finalists to perform the opening number.

But when it got to their (very brief) moment in the limelight, Ruby, 22, and Jazzy King, 24, made sure they stretched out their 15 minutes just that little bit longer by planting a smacker on each other.

Job. Done.

In other news, Mel B made a return to the judging panel after being struck down with a mystery illness earlier this week.

Former judge Tulisa stood in for Mel on Saturday night’s show, which saw the former Spice Girls’ act, Andrea Faustini leave the competition.
