Britney Spears wrote a message of thanks to Justin Bieber on Wednesday as she shared a video of herself dancing to his music on Instagram.
The 40-year old played the track 'I Don't Care' by Bieber and Ed Sheeran as she frolicked around her living room in a red crop top and tiny blue shorts.
Earlier in the day the pop superstar danced in the same outfit to Janet Jackson's All Nite (Don't Stop).
