Jessica Biel has legally changed her last name to Timberlake.

The 'Playing For Keeps' actress - who married singer-turned-actor Justin Timberlake, 32, in Italy last October after dating for five years - has officially changed her last name but will continue to use Biel professionally.

A source told Life & Style magazine: ''It's all official! The paperwork is done and she's now legally Jessica Timberlake.''

An insider previously revealed that Jessica was planning to change her name shortly after she and Justin exchanged vows.

The source said at the time: ''She said she's changing her last name legally and Timberlake is the coolest last name she has ever heard.''

The 'Total Recall' actress tied the knot with the 'Mirrors' singer following four days of celebrations at the luxurious Borgo Egnazia resort in Puglia, southern Italy, almost a year ago and the couple previously said they couldn't have asked for a better day.

The 31-year-old actress said: ''It was a total fantasy experience.''

The former N' Sync singer serenaded Jessica with a romantic self-penned ditty on his guitar as she walked down the aisle in a pale pink Giambattista Valli Haute Couture gown.
