UFC champion Ronda Rousey traded the Octagon for the WWE ring on Sunday when she teamed up with Dwayne “The Rock” Johnson to take on Stephanie McMahon and Triple H in a surprise appearance at WrestleMania 31.

The highly entertaining bit came shortly after The Rock interrupted the long-winded McMahon and H, who were gloating about their empire. Then after The Rock talked quite a bit of smack himself, he ventured to the ringside audience to fetch Rousey, who was there with her friends.

Rousey jumped the barricade and headed to the ring. The crowd went wild. And while the audience (and this writer) would’ve loved to see a full-on tag team match involving this foursome, the two couples traded only a few blows. Rousey, of course, came out on top, getting a good hip toss on Triple H.

Rousey also threatened to put McMahon in what looked like the arm bar that allowed her to beat her last UFC opponent in 14 seconds.

Hmm… WrestleMania 32 could be very, very awesome.
