Robbie Williams and Ayda Field have made it official.

The couple, who met back in 2006, exchanged vows Saturday in front of about 75 friends and family members at the UK pop star's Beverly Hills home.

"The ceremony was very beautiful and romantic," a source said.

"At last, Rob is happy," the star's dad, Pete Conway, told the News of the World. "That's what you want for your kids. This is the happiest I've seen him. Ayda is so beautiful, so delightful, so lovely and just so right for him. They are brilliant together."

Ayda Field is now Mrs. Robbie Williams!

After the romantic 30-minute ceremony, guests enjoyed a cocktail reception followed by a gourmet sit-down dinner. Happily ever after to follow.
