The MMA world watch on in astonishment as Ronda Rousey lost her second consecutive bout.
The former women’s bantamweight champion was blown away by Amanda Nunes in a matter of seconds; 48 to be exact.
Nunes’ first round victory saw her retain her women’s bantamweight championship in the main event of UFC 207 on Saturday.
A big right just seconds into the fight noticeably put Rousey on the back-foot from which she never recovered.
The humiliating defeat comes 13 months since her shock loss to Holly Holm in November 2015.
Here are the best tweets reacting to the stunning bout.
More I look at replays, worse it gets. Ronda Rousey took 5 shots square in the face as hard as Nunes could throw 'em. Concussion city.— Skip Bayless (@RealSkipBayless) December 31, 2016

Ronda Rousey said she thought about suicide after her loss to Holly Holm. This is her life. Cant imagine how devastated she is mentally.— Taylor Rooks (@TaylorRooks) December 31, 2016
Rousey bullied and strutted her way to the top of her sport. She created dangerous resentment. Nunes wanted to hurt her. And she did.— Skip Bayless (@RealSkipBayless) December 31, 2016
Every time Ronda Rousey gets hit she looks like she's never been punched in the face before and doesn't know why it's happening. #UFC207 .— Tyler Boeh (@TylerBoeh) December 31, 2016

Ronda Rousey has apparently left the arena. No surprise. She hasn't talked to the MMA media in over 13 months.— Arash Markazi (@ArashMarkazi) December 31, 2016
Rousey widened the door for Women's UFC but cant take the heat when competitors surpass her. You don't get to be cocky AND a sore loser.— Lacey Nycole (@LaceyNycole) December 31, 2016

The above video brings to you the official UFC weigh-ins before UFC 207 - which kicks off on Friday night in Nevada.
Among those weighing-in were headliners Ronda Rousey and Amanda Nunes, who will go head-to-head for the Women's Bantamweight Championship.
Other MMA stars that hit the scale included Dominick Cruz and his opponent Cody Garbrandt, as well as T.J. Dillashaw and John Lineker.
Bantamweight champion Dominick Cruz packs for his trip to Las Vegas, where challenger Cody Garbrandt visits a chiropractor.
Fellow bantamweight TJ Dillashaw - a former teammate of Garbrandt and former opponent of Cruz -- also arrives in town with that weight division's belt on his mind.
Which fighter are you most looking forward to seeing in action?
