Entertainment Tonight said McHugh wore a white strapless gown with a full tulle skirt, while Stamos donned a black suit, white shirt and black bow tie for the occasion. After the ceremony, the couple's closest family and friends attended a private celebration at his Beverly Hills home.
A police statement says Caitlin McHugh was away from her room Friday evening when a crook or crooks got in and took several items of jewelry.
While she was thankfully not in her room at the time of the incident, the Beverly Hills Police Department stated that the burglars broke in by unknown means and stole roughly $165,000 worth of jewelry, which was on loan from the Neil Lane collection. The room was unoccupied at the time and there are now no suspects.More news: City pays for Sterling's big miss

Stamos was previously married to actress Rebecca Romijn from 1998 to 2005.
"I hope [to have kids]", Stamos told ET in November, before McHugh's pregnancy announcement.
He posted an illustrated picture of a couple embracing at Disneyland on his Twitter account and he captioned the image: "I asked...she said yes!"
He admitted: "It kills me that my parents aren't here to be part of this, but I know it probably wouldn't be happening if they weren't up there. She's a gentle, kind, graceful soul who would be a good mother." .
