and gyrated throughout, even letting one of her dancers bounce on top of her as she lay on the floor.

The rest of the audience, including the Kardashian sisters, danced and clapped along but when the camera panned to Ora, 23, the look of disdain on her face was clear for all to see.

Throwing shade at Minaj, Ora couldn’t even manage a smile at the pint-sized rapper’s moves as she sat beside her designer pal, Jeremy Scott.

Dressed in a red full-length gown with a thigh-high split, Ora’s unimpressed expression has already been made into a .gif and is being shared on Twitter.

Just like her performance on Sunday night at the Forum in Inglewood, California, Minaj’s real video for the song left little to the imagination.

When it was released last week it broke the record for the most viewed music video in 24 hours – beating Miley Cyrus’ Wrecking Ball.

Giving Cyrus a run for her money – twerk-wise – she danced all up on rapper Drake, 27, who just sat in a chair staring in awe and taking the lap dance in his stride.

The 31-year-old also dons several bootylicious outfits as she moves throughout the dance jam which heavily samples Sir Mix-A-Lot’s 1992 hit Baby Got Back.
