Mark Wahlberg has finally made it official! The actor and his longtime girlfriend, model Rhea Durham, tied the knot on Saturday, PEOPLE has confirmed.

The couple, who have three children – Ella Rae, 5, Michael, 3, and 10-month-old Brendan Joseph – were married Saturday in an intimate and romantic ceremony attended by their children and about 12 close friends and family at Good Shepherd Catholic Church in Beverly Hills.

Wahlberg donned a dark suit and the bride wore a white strapless Marchesa dress with silver embroidery and a Neil Lane diamond-and-platinum cushion-cut ring complemented by a diamond bracelet and earrings. "She looked like a princess and beyond stunning. Mark looked ecstatic," says an eyewitness shortly after the ceremony, which lasted for about 45 minutes in the church, which was decorated with candles and pink and light purple roses.

The groom-to-be, 38, spent a quiet pre-wedding moment alone at the church Friday afternoon. Wahlberg, looking happy and relaxed, sat down in the front row before returning home to his Beverly Hills home for a small gathering.

Wahlberg revealed earlier this year his plans to wed Durham, 31. "We're talking about August," he told PEOPLE. At the time, he had yet to decide whether he would marry in his Boston hometown. "It will be in a Catholic church somewhere."

As for adding more children to their brood? "I'm the youngest of nine," Wahlberg said, adding that the final count will be "however many Mom wants to have."

Wahlberg, who is the executive producer of HBO's hit show Entourage, will next star in the Peter Jackson-directed feature film The Lovely Bones opposite Rachel Weisz, in theaters on December 11.
