Blonde Electra sisters Jazzy and Ruby King proved to be a controversial choice when they were selected to be among the 16 finalists on this year's X Factor.
And weeks after their elimination, they've put themselves firmly back in the spotlight for sharing what was perceived to be a rather inappropriate kiss during the show's grand final on Sunday.
The eccentric siblings, who were the first of the finalists to be booted off the show, took to the stage to perform with all of the returning and remaining acts when they decided to lock lips.

Dressed in high-waisted miniskirts with glittering bra tops with braces, the duo shared their kiss within feet of Mel B and their former mentor Louis Walsh, who seemed bemused as he looked on.
And while it might be quite some time until he shares his opinion on the matter, fans took to Twitter within seconds to express their outrage.
'BLONDE ELECTRA. You should NOT kiss your sister like that,' tweeted radio personality Lucy Horobin.

Made in Chelsea's Fran Newman-Young also appeared to be particularly unimpressed , as she tweeted: 'Well that sibling kiss was weird... I wonder if there will be any more desperate publicity stunts this eve.'
Actress Tracy Ann Oberman wrote on the micro-blogging site: 'While family on the bed watching #XFactorFInal even the dog looked up and snorted at the Blonde Electra kiss #awkward.'
Soon after their October elimination from the ITV ratings juggernaut, the sisters spoke to MailOnline about leaving the show so early in the competition.

Jazzy, 24, said: 'Leaving week one was a bit of a shock, I didn't think we'd leave this soon. But we knew it was coming and week one, week six, it doesn't really make a difference.
'I'm so proud of the both of us, we desperately wanted to get into the live shows and we did. We don't care - we're just happy we got through this far.'
Ruby, 22, added: 'We took the show one day at a time and we just had fun, and that's all that matters to us. We were ourselves and we had so much fun on the show.
'And I think we nailed Kids In America with the theme. I loved the hula hoops and the dress and the green eyebrows. It was incredible and it really represented who we were.'
