Gwyneth Paltrow has delighted Glee fans by making a guest appearance at the TV hit's live stage show in London.
The production at the 02 Arena features the popular programme's cast performing their biggest hits.
Hollywood star Gwyneth, who was showing her support for husband Chris Martin and pal Beyonce when they played Glastonbury last weekend, came on stage to sing the track Forget You.
The actress - who has a home in north London with Coldplay frontman Chris and their two children - appeared in season two of the high school song-and-dance series, playing supply teacher Holly Holliday.
During last night's performance of Glee, Santana Lopez (played by Naya Rivera) had just told fellow cast members and audience that she had been named sexiest Glee Club member during the tour when she was interrupted by the arrival of Gwyneth, who dazzled in a black mini-dress and then challenged her to a sing-off.
The Oscar-winning star launched into her cover of the Cee Lo Green chart-topper, accompanied by the rest of the cast and massive cheers from the crowd.
The US-based show also featured references to the royal wedding when couple Kurt Hummel (played by Chris Colfer) and Blaine Anderson (Darren Criss) compared themselves to the Duke and Duchess of Cambridge.
Chris joked: "I'm Kate to your Will. I'm Harry to your Pippa, God willing." The actor is a massive fan of the royal couple and has spoken before about how excited he was about the royal wedding.
