While many covered up in the cold, Serena Williams spent Christmas in what looked like underwear.
The 42-year-old tennis player spent the festive day enjoying some water sport activities in a very skimpy bikini.
Serena looked happy and relaxed as she ate lunch aboard a yacht with her friends in Miami, Florida.

Safety first: The tennis played donned a life jacket as she prepared to
enjoy some water sports activities
Wearing a white halterneck bikini top with a black lace trim and all black
bikini bottoms, the U.S. star wasn't bothered about showing off her body.
Serena pushed her hair back with a simple headband and modelled her muscular
physique as she laughed with her group of friends.
Having a laugh: Williams appeared to be enjoying herself as she fooled
around on an inflatable towable with her friends
Easy does it: The group looked as though they were going to fall in the
water as they joked around with one another
At one point it looked as though the group were in danger of falling in
the water as they piled on top of Serena.
The sports star is known for having a fuller figure and is not afraid to
show it off, but her older sister Venus isn't so confident about hers.
The 42-year-old recently admitted that she had slimmed down after swapping
steak for salad.
Festive fun: The group were obviously happy to spend Christmas Day
outdoors in Miami Beach rather than at home
Venus must have spent Christmas resting up after falling ill due to
suffering from Sjogren's Syndrome.
Her sister on the other hand made the most of the U.S. sunshine and
certainly appeared to have a very merry Christmas.
