Lady Gaga calls out former UFC champion Ronda Rousey

Pop star Lady Gaga has shared some fighting words with former UFC champion Ronda Rousey for poor sportsmanship before her title-losing fight with opponent Holly Holm.

"THAT'S WHAT YOU GET FOR NOT TOUCHING GLOVES!" Gaga posted to Instagram alongside a picture of Holm landing a punch on Rousey.

In UFC it is tradition to meet your opponent in the middle of the ring before a bout and to touch gloves as a sign of respect.

Before the fight Holm held her gloves out to Rousey anticipating the touch, only to be rejected.

Rousey was later knocked out by an unblocked kick from Holm in the fight's second round.

Gaga was joined by countless more on social media who called Rousey out for the snub on social media.
