Ronda Rousey's BF Officially Divorced

Ronda Rousey just got one step closer to marrying her boyfriend ... 'cause Travis Browne's previous marriage is finally officially over ...TMZ Sports has learned.

Browne married fitness model Jenna Webb on January 9, 2015 -- but things went sour quickly and they split up on June 3rd.

Webb later accused Browne of domestic violence -- though he adamantly denied the allegations. The UFC investigated but determined there was no evidence to prove Browne attacked Webb.

Now, the judge has finally signed off on their divorce -- making it official on February 8th ... which means Browne is technically single again and free to marry whoever he wants.

Rousey has already said she wants to have his babies ... so, no pressure bro.
