Lindsey Vonn shows off thong while celebrating her birthday


Lindsey Vonn is one of the most decorated skiers we have ever seen. Now that her career is over, she has a little more time to reflect on her past achievements.

Vonn, who turns 38 this weekend, sent out a photo on Instagram Friday showing off her toned backside while letting her fans know how grateful she is to be in her current position.

"When I look in front of me sometimes I can’t believe how far I’ve come. Who knew ski racing and surgeries could bring me here. Thankful for everything I have; my love @subbanator, my family and my friends. Don’t forget to appreciate life because it’s short. Cheers to today!," she wrote on Instagram.

Vonn is engaged to New Jersey Devils defenseman PK Subban.
