Lady Gaga takes shot at Rousey after UFC 193 knockout loss

Ronda Rousey has seen more support from celebrities before, during and after her fights than virtually every other UFC fighter combined, but don't count Lady Gaga among her biggest fans.

While J.J. Watt, Howard Stern and Alicia Keys all sent out messages in support of Rousey before the fight, Lady Gaga wasted no time reveling in her downfall following the knockout loss to Holly Holm at UFC 193.

The "American Horror Story" star took to Instagram -- and her 12.3 million followers -- to take a shot at Rousey for poor sportsmanship after she refused to touch gloves with Holm during the customary pre-fight stare down.

"That's what you get for not touching gloves!" Gaga wrote in the photo posted.

Rousey has received her fair share of criticism following the fight after suffering her first defeat in 12 bouts.

Lady Gaga joined Rousey's biggest rival Miesha Tate as the most vocal opposition to the former champion following the loss to Holm on Saturday night.

Rousey was transported to the hospital immediately following the knockout and has yet to make any kind of public statement since leaving the Octagon after the defeat.
