Amir Khan and Kellbrook ahead of their fight on February 19,
Khan, a former light-welterweight champion world champion, has agreed to allow Brook to meet him at the catchweight limit in Manchester of 149lbs.
The Bolton hero believes that his Sheffield rival is too happy in the ring to threaten his legacy.
Khan stated: "When I look at my life other than boxing, it is fairly clean and that will help you."
"I am 35 years old, Kell is about the same age as me, but Kell's life is quite different from mine.
"We live opposite life-styles. I'm a family man who does not drink alcohol. I live a clean lifestyle. Kell doesn't believe so.
Brook displayed a career-defining performance in 2014, when he took the IBF title from Shawn Porter in the States.

Khan believes he saw evidence of this last November during their first press conference.
Khan said, "What got me where I am was hard work and dedication, discipline, focus, and focus."
We know Kell to be one of those guys who can get off the rails after a fight. He'll disappear for a few weeks and gain a lot of weight.
"He looked extremely unhealthy and unfit if you saw him at the press conference."
"I was unsure if he would be in the best shape in ten weeks when the fight comes around. However, I had been training for the past couple of months."
