Striking a united front, both the bride and groom wore custom designs by Giorgio Armani. While Gruffudd, 33, opted for a midnight blue suit of wool crepe, his bride, 36, took a slightly more traditional approach – walking down the aisle in an antique white strapless gown made of cascading tiers of organza.
"It was an intimate gathering," says a source close to the groom of the event, which took place at the fashionable One and Only Palmilla Hotel in Los Cabos, Mexico. "Friends and family traveled all over the world for it."
The couple, who first met on the set of 2000's 102 Dalmatians, had kept mum about their long-term relationship and engagement. But at the MTV Movie Awards in June, a proud Gruffudd beamed while discussing his upcoming nuptials.
"I am heavily involved. Both Alice and I are doing it ourselves," he told PEOPLE at the time. "We did the invitations, which was enough of a burden, and now of course everybody's saying they want to come – so we're over by about 20 people, but we'll work it out."

The wedding "is not back home in Wales," said Gruffudd. "We thought we'd celebrate our new life here. We moved here about five years ago. We've embraced it and are loving living here."
Evans recently completed filming the drama Dangerous Parking, with fellow U.K. actress Saffron Burrows.
Gruffudd, who began starring in the Fantastic Four movie series in 2005, recently reprised his role as the Marvel Comics hero Mr. Fantastic in the sequel Rise of the Silver Surfer. He has also lent his voice to another hero in the animated movie Agent Crush and will appear alongside Julia Roberts and Ryan Reynolds in Fireflies in the Garden.
