Katherine Heigl looked lovely in a backless dress at the "One for the Money" Paris premiere yesterday. She swept her hair up in a vintage 'do and cheerfully walked the red carpet with her husband Josh Kelley.

Her film centers on 30-year-old Stephanie Plum (Heigl) who goes to work at her cousin's bail-bond business and begins investigating her first case. On its opening weekend the film came in number three at the box office, earning $11.8 million.

She also stars in the upcoming film "The Big Wedding" about a divorced couple (Robert De Niro and Diane Keaton) who turn on the charm and masquerade as if they were still married.
