Kell Brook smiles after being seen in the ring for first time since he was filmed snorting white powder.

KELL Brook has a smile on his face as he enters the ring for the first time since being filmed snorting a line of white powder.

The world champion boxer, 36, was caught bending over a glass table as he partied at his Sheffield home.

Seconds Away revealed the footage back in January which showed Brook looking worse for wear.

He has since been pictured for the first time at a gym in the Canary Island, Fuerteventura.

Brook posed in the ring at Baileys Gym wearing gloves as he appeared to be in winter training.

The gym shared the photo to their Instagram tagging Brook – which he re-posted to his story.

Brook took to social media earlier this month to apologise for his behaviour.

He wrote: “I messed up, I hold my hands up & want to apologise to my family gym friends & fans.

“It’s no secret that I struggle with mental health & I’m finding retirement really hard.

“I’m actively seeking the help I need to get me on the right path. Again I apologise for the hurt I’ve caused.”

A source said at the time: “He had a bit of a gathering at his house where people were drinking spirits and smoking.

“He was snorting white powder.”

However manager Terry Thompson insisted it was “a joke”.

He said of the party clip: “This is a thing that has sort of got out of hand.

“They were at his house, they were having a laugh.

“They were joking about things.

“He said to them, ‘Film me having a laugh’.”

Asked if the powder was cocaine, he replied: “No.”

The clip shows a heap of white powder next to a plastic “wrap” as the star mumbled “nice”.

Brook then shadow boxes in front of a framed portrait of him having won the IBF welterweight title in 2014.

Wife Lindsey, 35, and their three children were believed to be away at the time of the gathering.

Brook announced his retirement in May after winning 40 of 43 professional fights.

But he said recently he would return to the ring for the right offer.
