"It's amazing," Nunes said during the post-fight press conference. "The more important thing is I'm happy with my life. This is the more important thing."

Nunes' girlfriend, Nina Ansaroff, is a UFC fighter in the strawweight division. She was in attendance for both the fight and Nunes' presser.

"Nina is the best training partner I've ever had in my life," Nunes said. "This girl is going to be the next UFC champion, I'm telling you ... This girl has so much talent, and she's going to get back in the cage soon and show everybody she's going to be the next champion of the UFC.

"And it means everything to me. This girl, she helps me with everything ... I love her."
