Jessie J is transforming her image into a more polished look.
The 'Price Tag' singer has had a complete style overhaul after changing her style team.
The 24-year-old star has split from long-term collaborator Karl Willett, who recently styled her 'Lazerlight' video and dressed her during her time as a judge on 'The Voice'.
Karl is also a stylist for singer Paloma Faith.
Now she is working with Cobbie Yates, the brother of radio DJ Reggie Yates.
She met him when he dressed his brother while he was co-hosting the British version of the talent show.
A source told the Daily Mirror newspaper: ''Jessie has worked with Karl for a long time but she decided it's time for a change and she gave him the elbow.
''They used to work really well together - Jessie even wanted Karl to dress her contestants on 'The Voice' at one point, because she wasn't happy with the style team on the show.
''But now they've gone their separate ways. He sent out an email last week confirming to all his fashion contacts that they are no longer working together, because there had been a lot of rumours flying around the industry.''
