It's official ... TMZ Sports has learned WWE legend Ric Flair is teaming up with his son-in-law, Andrade, to fight Jeff Jarrett and Jay Lethal in his "last match" ever.
For months, there had been speculation about who'd join Flair inside the ring for arguably the biggest night of his career ... so it's fitting he chose his daughter Charlotte's husband, Andrade.
As for their opponents, Flair and Jarrett have history going back to their WCW, WWE, and eventually the TNA days.
