Britney takes son Sean on stage
Britney Spears treated the crowd at her Hungary gig to a special guest appearance - from her son Sean Preston.
The singer was in Budapest as part of the European leg of her Femme Fatale tour and after she was lowered from the ceiling amid confetti and fireworks during her performance of 'Til the World Ends, she suddenly brought out her older son from the back of the stage.
Sean, six, dressed in jeans and a sweatshirt and wearing his Access All Areas backstage pass, clutched a microphone, but appeared a little overwhelmed by the screaming crowd.
Britney crouched down with Sean and whispered to him "stand up" and he greeted the audience with a smile and a wave.
Sean was a huge hit with fans and he joined his mother waving to the audience as they both disappeared through a hole in the stage.
Britney has now tweeted a picture of Sean's big moment.
She recently revealed she thinks Sean and five-year-old Jayden James will follow her into showbusiness.
Britney said: "When I'm on the road they come with me and they love being on the road. When I was younger I was always on the road and it's always exciting.
"They are in awe, they come home and copy the dancers' moves and try to get on their heads and do spins and do all these things. They'll probably be in the entertainment business, definitely."
