Cat Deeley is off the market.

The So You Think Can Dance host, 35, wed Irish comedian Patrick Kielty, 41, in a hush-hush ceremony in Rome, Italy on Saturday, Us Weekly reported.

Deeley and Kielty were reportedly married at St. Isidore's College Church in a small service officiated by the priest of Kielty's family parish in Northern Ireland.

"It was the most beautiful, gorgeous, chic and romantic wedding I've ever been to," a source told Us. "The whole thing was sprung on the guests at the last minute, but you can tell a lot of time had gone in to the planning."

Deeley wore a "gorgeous" dress with "with ruffles all the way down," according to the source.

About 60 guests reportedly attended the ceremony, which was followed by a low-key reception.

"It finished before midnight and everyone was civilized and well behaved," another source told Us. "It wasn't a wild party."

Deeley and Kielty first met in 2002 when they hosted the U.K.'s Fame Academy reality series together and reportedly began dating about a year ago.
