Lindsey Vonn Goes Birthday Bowling In Stilettos With Lewis Hamilton

Lindsey Vonn put her full athleticism on display Tuesday night ... proving she can still bowl like a champ -- even in stilettos.

Vonn celebrated her 32nd bday last night with some help from racing legend Lewis Hamilton ... who met Vonn at a high-end bowling alley where they hit the lanes all night long.

The two have been friends for a while -- and while there have been rumors about them dating, neither side ever confirmed a relationship.

In fact, last night Vonn only referred to Hamilton as her "fast friend."

Check out the video ... Vonn looked like she had a blast and couldn't wait to show off her new Jimmy Choos.

Happy bday!
