7th Heaven's Mitchell Marries; Biel Plays Bridesmaid

7th Heaven star marries longtime beau Wednesday in a ceremony attended by former costar Jessica Biel

It was a ceremony made in Heaven.

Beverly Mitchell, best known as Lucy Camden on 7th Heaven, swapped vows today in Naples with Michael Cameron, with former TV sisters Jessica Biel (accompanied by Justin Timberlake) and Mackenzie Rosman among the seven, natch, bridesmaids.

About 100 guests attended the ceremony, a rep for the actress tells E! News. However, the publicist says that earlier reports claiming Hilary and Haylie Duff were also in the bridesmaid brigade were "inaccurate."

The 27-year-old bride wore a classic white strapless Melissa Sweet gown, while the groom, also 27, sported a traditional black tux by Kenneth Cole.

Biel and Timberlake made headlines a few days earlier after paparazzi caught the couple smooching on the streets of Rome. They eventually made their way to Mitchell's rehearsal dinner on Tuesday night.

Cameron, an accountant, proposed to Mitchell on New Year's Eve 2005 in Colorado, sealing the deal with a 3.5-carat yellow diamond ring by Louis Glick.

Mitchell, whose credits also include The Crow: City of Angels, Saw II  and guest roles on Quantum Leap, Melrose Place and Baywatch, also released a self-titled country album last year.
