Cheryl shows off her dance moves as she shares coaching tips in new The ...

The first live shows are set to take place this this weekend.

And on Friday, the BBC released new images of The Greatest Dancer's three Dance Captains: Cheryl, 35, Oti Mabuse, 28, and Matthew Morrison, 40, as well as dropping a zestful trailer for the live shows, which shows the trio coaching their chosen dancers.   

For the two images and her dance segment in the video teaser, former Girls Aloud star Cheryl slipped into a metallic silver tracksuit bottoms and a sheer blue net top, with a coordinating shiny bra-let underneath.

The star donned purple boots with a chunky gold heel and accessorised with large hoop earrings to finish off her look. 

The brunette beauty's long tresses were styled loose and straight, and her natural beauty was enhanced with a subtle make-up look. 

Oti Mabuse wore a figure-hugging multicoloured sequinned mini dress for the promotional shoot, which she teamed with metallic gold stilettos.

Matthew Morrison showcased his flamboyant sense of style in purple trousers and a  patterned jacket, with a white T-shirt and trainers giving his look a more casual feel.  

In the video teaser, the three dance captains show off their moves, with brightly coloured smoke adding an extra dash of pizzazz to the sequences. 

The short trailer also shows the trio separately coaching their dancers in studios, ahead of their live television performances. 

In one clip, Cheryl can be heard telling Liverpudlian dancers Eleiyah Navis and Harry Smallman to 'push it 'til your body hurts' while they practice their routines, as Oti Mabuse yells at her dancers to 'focus.'
