Audrina Patridge has tested some bold hair hues -- purple, pink and dirty blond. But the Hills alum just returned to her natural color -- and her loyalists from the iconic MTV program are to thank for it.

"@brianacisneros Bringing me back to brunette," Kirra's mama captioned the Instagram image above, while giving her stylist a shout-out. "#carselfie (ps this is for my diehard hills fans that have been saying go back to dark haha)."
