Pop star Jessie J has unveiled a dramatic transformation after ditching her stylist Karl Willett.

The Price Tag hitmaker, known for her eclectic wardrobe and standout style, has had an image overhaul courtesy of Reggie Yates' brother Cobbie.

The 24-year-old star unveiled her glamorous new image ahead of her gig at the Roadhouse in Camden.

Wearing a short Vivienne Westwood metallic dress and strappy sandals, she teamed her feminine outfit with natural make-up and long, tumbling locks.

Jessie J recently admitted that her signature look, which usually consisted of bold lips and an angular bob, made her look like a "cartoon character".

The singer's trademark look usually consisted of heavy black eye shadow, bright lipsticks and flamboyant outfits.

Speaking to Grazia magazine, she said: "I started to look like a cartoon character with the fringe and the cat suits. Yes, I want to change and mix it up. I want to change my hair, change my style. I want to be allowed to grow."

The Essex beauty reportedly parted ways with Willet, who was in charge of her wardrobe during her stint as a judge on BBC talent show The Voice, after growing tired of her look.

He has been replaced by up-and-coming fashion expert Cobbie Yates, who was hired after she met him on the set of The Voice.
