Jesinta rocks her bikini body

We might be in the midst of winter but Jesinta Campbell has already got her bikini body ready for summer.

The former Miss Universe Australia shared a sexy snap in a high-cut white swimsuit from a magazine shoot with her 135,000 Instagram followers yesterday.

The girlfriend of WA-raised AFL player Lance "Buddy" Franklin looked as though she had just come out of the sun, given her glowing tanned skin.

Campbell turned 23 on Saturday and was lavished with attention from Franklin after his Sydney Swans football game, with the couple sharing a tender kiss during a gathering with friends.

"My love. Thanks for making my week so special," Campbell captioned the intimate Instagram snap of the loved-up couple, who have been together for more than a year.

Earlier in the day Campbell had pulled together a fan club, who all sported "team Buddy" T-shirts, for her boyfriend as he got out on the football field for his 200th AFL game.
