Pop princess Britney Spears
The video, which was called "Best Wedding Speech Ever – Britney, Better Work B***h, was kept relatively under wraps. But when Britney came across it and shared it on her Twitter account, thousands of her followers clicked on to see what exactly she was so excited about.
"Ummm....this wedding toast is INCREDIBLE!!! I want IN on the 10 year anniversary performance!!! #WORKBXXCH," posted Britney alongside the video link.
In the clip, best friend Bradley started his speech by acknowledging his and the bride's absolute love for Britney.
"We've always been there for each other," said Bradley. "But here's the thing. There's someone else that's been there with us along this journey together. Her name is Britney Spears. In a way she's sort of been the soundtrack of our lives.
"We all know that marriage takes love and care. But marriage also takes a lot of work. So you better work b***h."
Britney and her family have just come back from holiday in Hawaii
Bradley then whipped off his jacket as a group of professional dancers took to the dancefloor to perform their own routine to Work B**Ch. As the mastermind behind the idea, Bradley — who hasn't performed or danced since he was a teenager — played the vivacious role of Britney down to a tee.
The bride Stephanie looked thrilled to watch the performance as she mouthed along to the lyrics and was pulled up onto the stage to dance the final moves with her best friend.
Britney's tweet comes just days after she posted a series of photos of her and her family on holiday in Hawaii. The mother-of-two looks flawless, showing off her enviable body and glowing tan in a bright pink bikini.
Surrounded by her two boys — Sean Preston, eight, and seven-year-old Jayden James — and her new man David Lucado, 32-year-old Britney couldn't look happier.
