Beneath all that makeup and perfectly blown-out hair is an Audrina Patridge like you've never seen her.

The Hills alum bravely went through a dramatic makeunder conducted by -- the same site that stripped Sammi "Sweetheart" Giancola of her false eyelashes and bronzer in December.

In her interview, Patridge, 26, admitted that on a normal night she spends 45 minutes on her makeup and two hours on her hair. For proof of endurance, went straight to her glam team.

"I'll use twenty to thirty products: several eye shadows, three or four brushes, a highlighter, concealer, foundation, mascara, lip gloss, lipstick, powder, lashes…and so on," said her makeup artist Spencer Barnes of Solo Artists/NARS.

Added the star's longtime hair pro Jonathan Hanousek of Executive Artists, "I usually blow dry it with a round brush and set it in rollers, then curl it with a curling iron, then loosen the curl. Yup. About two hours."
