Serena and Wozniacki relax together and show off their bodies after long tennis season

Serena Williams and Caroline Wozniacki have been having a great time since the end of the WTA Tour season.

Wozniacki ran the New York Marathon last week, before the two tennis stars were spotted at a New York Knicks basketball game on Tuesday.

And now the two top ten players have found a new source of fun, hanging out by a pool and taking pictures together. 

World No 1 Williams posted this picture of herself to Instagram on Saturday afternoon

Wozniacki was also documenting the holiday online, posting this with the caption 'Life is good! #pooltime'

World No 1 Williams posted a number of pictures to her Instagram on Tuesday of the pair by a pool, including shots of each of them showing off their bikini bodies.

Wozniacki meanwhile posted her own picture to Instagram with the message 'Life is good! #pooltime #nofilter'.

The pair were also joined by the pool with a pair of Brirish racing drivers, Paul Rees and Will Stevens.
