The Libertines guitarist has taken to Instagram in his search for a "male bassist, male guitarist, male drummer and a frontman" for a new project called The Heartless.

Carl shared a poster which he described as a "casting call", and he stated the band members "must be able to play and act".

The post, which was also shared on The Libertines' social media platforms, features the 40-year-old musician wearing a pair of sunglasses, and also encourages potential candidates to email [email protected] if they think they have the suitable credentials.

It's a busy time for Carl as he recently updated fans about plans for The Libertines' fourth studio album, admitting he has to lock himself away "in a little bunker" because "can't work under the pressure" of thinking he needs to pen a big hit.

He said: "I tend to lock myself away in my little bunker as I can be lazy, I can't work under the pressure of thinking I need to write a f***ing hit.

"I've got a lot of ideas for this album.

"Ones which I need to chat about with the boys."

And the lead guitarist previously said the upcoming record - a follow-up to 2015's 'Anthems for Doomed Youth' - will be very much in the vein of their 2002 debut album, 'Up the Bracket'.

He told BANG Showbiz: "We have a special plan for that actually. I can't really say anything about it, but it is really exciting and we are all in a really good place for that.

"The project we are looking at is pretty immersive and I think it will be more like how we were for our first record."
