Brock Lesnar tells it like it is no matter what — or who — he’s talking about. And he’s not mincing his words to please WWE fans or even his bosses at the pro wrestling company in the run-up to UFC 200, where he’ll enter the Octagon for the first time in five years and possibly lose.

“I really don’t give a s—,” Lesnar said in a media conference call about whether he worries a negative outcome in his fight against No. 8-ranked heavyweight Mark Hunt will affect his WWE draw. Lesnar is currently a top draw for the pro wrestling company and has agreed to appear at SummerSlam on Aug. 21.

Lesnar also doesn’t much care for the opinion of WWE Chief Brand Officer Stephanie McMahon, who recently told Business Insider that the company is “not supporting the fight necessarily.”

“I don’t care what she says,” Lesnar said with a chuckle, noting he hadn’t read the interview.

For Lesnar, this MMA bout isn’t about furthering his career, but getting revenge — not on Alistar Overeem, who beat Lesnar at UFC 141 in December 2011, the last time Lesnar appeared in the Octagon, but on diverticulitis, the intestinal illness that he has repeatedly blamed for prematurely ending his MMA career.

“It’s no mystery that I was forced out of this competition because of an illness I had. I tried to be the competitor I wanted to be, but it’s kind of hard to do when you have a disease,” the 38-year-old former heavyweight champion said. “I’m in a whole different spot both mentally and physically, and before I become a 40-year-old man, I want to get back into the cage.”

Whether his venture back into MMA will draw any new WWE fans, Lesnar said, “I really don’t care. This isn’t about my fans. This is about me living my life, being the person I want to be.”

He added: “Granted without the fans none of us would be able to do this — I get that. But I don’t sit up and night wondering if my drawing power’s gonna be good or are my WWE fans gonna watch me do this. I don’t give two s—- about that. This is about me, and I want to get in there and be an athlete again.”
