No word yet on any firm future fight plans, but the entire planet definitely wouldn’t mind seeing Diaz and Conor McGregor fight again, because the trash-talk has always been epic between the two.

Here’s TMZ Sports:

Nate Diaz is a daddy!!!

The 33-year-old UFC superstar and his longtime girlfriend, Misty Brown, welcomed a healthy baby girl at a California hospital on June 6 … according to public birth records obtained by TMZ Sports.

Nate and Misty — both from Stockton, CA — have been together for years. They’ve been posting photos of each other online … dating back to 2012.

We’re told the baby is happy and healthy, and the families are stoked.

We reached out to Nate’s camp for comment — but a call to the fighter’s rep was not returned.

Congrats!
