AceShowbiz - Justin Bieber seemingly mocked Ronda Rousey on Twitter following her UFC 207 loss. Without specifically mentioning the December 30 fight that took place at the T-Mobile Arena in Las Vegas, the singer cryptically tweeted, "You just got knocked the f**k out."

you just got knocked the fuck out

Justin Bieber and Ronda Rousey have a history of feud. She once slammed him for refusing to take a picture with her sister. He apologized later, "I don't remember this happening so, Ronda, I'm sorry. Don't kick my ass!" However, his next comment was a subtle diss at the female fighter as he referred to her loss to Holly Holm in 2015, "Did you see Ronda Rousey? She got knocked out cold! Oh my God, she got knocked out so bad."

Ronda Rousey was defeated by Amanda Nunes in just 48 seconds on Friday night. It was Rousey's first fight since her shocking loss in 2015. Celebrities like Anna Paquin, Josh Groban, Jordin Sparks, Michael Strahan, Rosie O'Donnell, Mark Ballas, Mario Lopez, Reggie Bush, Christina Millian, Beth Behrs and Patrick Wilson reacted on Twitter.

Nunes herself celebrated her win by posting a photoshopped image of her holding a championship belt while pushing an angry looking Ronda in a baby stroller.
