Serena shows off her booty-ful vacation in Jamaica

Serena Williams may have fallen short of winning the title at the Australian Open last month, and tying Steffi Graf's record for career Grand Slams, but she sure isn't sulking.

She's in Jamaica helping build schools and showing off her beach bod while staying at the spectacular Canoe Cove.

It's all very impressive. All of it. The guys at TMZ were especially impressed by the sight of Serena in her swimsuit. You probably will be too. Check it all out in the video above.
