Cheryl is one of three judges on the BBC show, and she joined the others for a dance on stage last night wearing a black leather sleeveless top, red and black skirt and black flat boots. Despite the probable warmth in the studio, she kept her legs covered in a pair of sheer black tights. Keeping with the grungy theme, Cheryl wore a dark colour on her nails, and had a heavy black eyeshadow accentuating her eyes. She completed the look with a pair of large hoop earrings.
Famed for her luscious locks, Cheryl wore her hair down straight over her shoulders.
Cheryl was not the only one to dress up for the live show last night.
Fellow judge Oti Mabuse made sure all eyes were on her in a silver sequin blazer dress, £345, from Whyte Studio.
The dancing professional took to Instagram to share the details of her look, revealing her matching silver boots were from luxury fashion brand Gina.
Oti paired the standout look with a simple bob hairstyle and lashings of eyeliner.
Presenter Alesha Dixon, meanwhile, plumped for a rainbow sequin minidress for her turn in front of the camera.
The dress featured a high neckline and wide sleeves, giving it a 70s feel.
Adding to the retro vibe, Alesha donned a pair of gold multi-hoop drop earrings.
She wore her hair up in an impressively neat topknot, which sat right on top of her head.
Letting the dress do the talking, Alesha wore muted makeup, opting for brown lipstick and smoky brown eyeshadow.
Cheryl has had a long and fruitful career since she appeared on screens way back in 2002. What is her net worth?
Former X-Factor judge Cheryl is worth a whopping £20 million, according to Spears.
The Geordie lass shot to fame when she starred and won Popstars: The Rivals in 2002, becoming one-fifth of successful girl group Girls Aloud.
The reality-show winners went on to become the biggest-selling girl band of the 21st century, notching up twenty consecutive top ten singles.
After Girls Aloud split in 2013, Cheryl enjoyed chart solo success with a string of number one hits.
