Rita Ora forms a very unlikely band with Jason Momoa and Jack Black during ... trends now

Rita Ora formed a very unlikely band with Jason Momoa and Jack Black as they put on an impromptu show in New Zealand.

The singer, 33, took to the stage to perform with the Game Of Thrones actor, 44, and the School of Rock star, 54, at a star-studded party earlier this week.

Jason and Jack are co-starring in the live-action Minecraft movie and celebrated the end of filming over the weekend with a group of their famous pals including Rita.

At the wrap party, the pair showed off their musical talents as they took to the stage with Rita - who is married to New Zealand filmmaker Taika Waititi - for an impromptu musical number.

Forming a very unlikely rock trio, Rita and Jack both belted out Stevie Nicks' smash hit Edge of Seventeen while Jason played guitar behind them.

Footage shared by their pal Vas J Morgan to Instagram showed Rita giving the performance her all as she jumped up and down while singing her heart out.

She cut an edgy figure in distressed denim shorts and a brown vest top, which she styled with chunky black boots as she appeared to have the time of her life on stage.

Jack cut a casual figure in a graphic T-shirt and colourful shorts, which he styled with brown loafers and a vibrant yellow hat for the performance.

Meanwhile, Jason showed off his signature style in brown trousers and a matching vest top, while he tucked his curled locks beneath a black bowler hat.

Jason was also joined on stage by his bandmates Mike and Kenny as they launched their new musical group Öof Tatatá at the star-studded wrap party.
