It seems that Beyoncé has fans in every walk of life and profession - and that goes for superstar tennis players, too.

Serena Williams recently used a day on the training court to pay homage to the singer, re-making her video for '7/11'  - which Beyoncé filmed in a hotel with her iPhone - on a GoPro camera and sharing it on Vogue magazine's website. (She's on the cover of Vogue's April issue).

Beyoncé apparently approves, as she posted the video on her Facebook page yesterday, saying 'So cute Serena Williams!'

Watch Williams's version - as well as the original - below:
