Audrina Patridge isn't afraid to show off her Hills to the world ... and we like it!

The reality star strikes some seductive poses for photographer Davis Factor. Factor, is the grandson of makeup mogul, Max Factor ... who is also co-creator of Smashbox Studios.

On her personal website, Audrina mentions that her Hills co-star, Lo, works for Smashbox Studios. Guess it pays to have connections!
