According to photos, McHugh, 31, wore a strapless A-line gown with plenty of tulle.
Meanwhile, a burglary took place at McHugh's room at a hotel in Beverly Hills while she was away, before the wedding.
Law enforcement sources tell TMZ, Caitlin was staying at the Beverly Hills Hotel Friday when she left - presumably for dinner - and came back to find burglars had broken into her bungalow and stolen around $165,000 in jewelry.
The weekend was not without drama, however, as the couple had to stop by the police station to report a robbery ahead of their big day.
Police officials suspect the robbery may have been an inside job as there was no sign of forced entry.
McHugh, a model and actress, is now expecting the couple's first child.
Stamos proposed to McHugh after dating for two years and learning that she was pregnant.
Stamos stars in Netflix's "Fuller House" and the original "Full House". "I've been practicing for a long time", Stamos joked.
"I've been waiting for the flawless girl for over a decade and she walked into my life", Stamos told People after announcing the good news. "So I called her parents to ask, and it was like, 'You better!'" he told People in December.
"I walked in, I went, 'Hey, are you stalking me?' She was like, 'No...' That's why I love her". "It was the look of a man who has wanted a family of his own but wasn't sure it was going to happen for him".
