We first saw Luke last year when he auditioned for The X Factor and famously told the judges he hadn't washed his hair in nine months...
After reaching the final and coming third on the show, Luke has got us wondering if he's jumping ship to the BBC and trying his luck on The Voice?
Earlier today, Luke was spotted with his guitar in hand in Manchester's Media City - the venue hosting the Voice's blind auditions.
Although his Twitter feed suggests he was simply there to "busk" and his rep has told Reveal that he is NOT auditioning, it is a coincidence!
The aspiring singer should be a pro at performing in front of a panel now and, if he was auditioning, he'll have to impress not one, but four of the music industry's finest.
Taking a spin in those big red chains this time round are returning judges Tom Jones, will.i.am, Kaiser Chiefs frontman Ricky Wilson, along with newly-appointed judge, Rita Ora.
Last week (23 September), Rita was confirmed as The Voice's latest recruit. Replacing former female judge Kylie Minogue, Rita said she was "so excited" to be a part of the show.
One judge who will be happy to see Rita sat alongside him as Blind Auditions begin is will.i.am. It's thought will was the driving force behind Rita's arrival as he has claimed it was his idea she join the show.
