There have been rumours doing the circuit suggesting Rousey was dating fellow UFC fighter Travis Browne and the bantamweight champion finally confirmed the news in a statement to ESPN.
"I don't talk about my personal life much, that's why it's called "personal life," Rousey said.
"It's true that Travis and I are in a relationship. I've really enjoyed the time we have spent together and getting to know one another.
"That's all I'm going to say about it."
Browne also confirmed the news with the suggestion the duo had been in a relationship for a while.
"She's my woman and I'm her man," Browne told MMAFighting.com.
"There's no boyfriend, girlfriend stuff. There's no dating. We're together.
"It's not weird. It's not something we have to adjust to. We've been doing that the entire time.
"She was doing her camps, I was doing mine without that thought process going through our head."
