Vonn, Hami more than just friends?

Lindsey Vonn, who turned 32 last week, was spotted having a blast with the Mercedes driver. The ski racer also tweeted a congratulatory message to Hamilon after the Austin race.

The two were found sitting quite close at the F1 Circuit of the Americas, a race Lewis dominated.

Vonn and Hamilton were seen together before as well, when the Briton took her out on a bowling date for her birthday.

Hamilton though still claims that he is very much single and wants to completely focus on racing and not to let relationships get in his way. Vonn has also insisted that the two are just friends.
