One is a champion in the cage and the other is a pop star on the stage.

And in a new Saturday Night Live promo, UFC fighter Ronda Rousey and musical guest Selena Gomez - who will sing Hands to Myself - joked about boys with castmember Cecily Strong.

Ronda declared that as strong independent women, they possess 'some serious girl power,' but the conversation soon turned to another topic as they agreed in girlish voices to 'call boys.'

Rousey also put the smackdown on Beck Bennett in a second promo.

The MMA bruiser - who turns 29 next month - is the first UFC fighter to host the NBC sketch series.

After the 31-year-old castmember delivered corny pick-up lines, the Olympic bronze medalist warned: 'Take your arm off me or I'll rip it off.'

Ronda rolled her eyes as the AT&T pitchman donned a wrestling singlet and a star-spangled cape - dubbing himself Beck 'The Wreck' Bennett.

'I'm a UFC fighter not WWE. We actually fight and don't wear costumes,' the 5ft7in athlete corrected.

When Beck attempted to put Rousey in a 'noggin lock,' she used her fourth-degree black belt in judo to flip him off of her.
