It's Tara 2.0!

She's always been known more for her wild partying than her fashion sense, but Tara Reid is showing off a glamorous new look these days.

The actress, 36, arrived at the Los Angeles premiere of American Reunion, the fourth theatrical film in the American Pie franchise, on Monday in a sophisticated white asymmetrical gown that showed off her tan, toned figure. Her hair was slicked back in a sleek ponytail and she accessorized with simple drop earrings.

Reid was joined by her co-stars including very pregnant Alyson Hannigan, who flaunted her growing bump in a green sequined mini, and Mena Suvari (in Christian Siriano).

Also on the red carpet: Jason Biggs, Eddie Kayne, Chris Klein and Seann William Scott.
