It comes to something when the big news coming from the X Factor is that an act has washed his hair - but I can't deny it, I was actually interested.
Mentor Louis Walsh has been on a campaign to get his young crooner to ditch his now famous (infamous?) locks for the live shows.
Having resisted for so long Luke had finally taken the plunge and give those dreadlocks a bit of a washing. I'm sure he used nice warm water, had a little massage, threw in a bit of conditioner... all the usual hair washing actions he's avoided for so long.
Am I thinking about this too much?
Anyway, Luke is said to be pretty pleased with the new look and is chuffed his hard-earned dreadlocks don't actually feel very different.
He's even had some highlights added. Honestly, it's too much information to take.
Luke's new found barnet is going to get an airing with none other than Nicole Scherzinger too. Luke jokes, "My hair didn't particularly smell to be honest but now it's had a good wash I'll definitely be burying my head in Nicole's face and seeing if it works!"
It'll be er, 'Shamazing'?
The X Factor continues at 8:00pm on Saturday and Sunday on ITV
