The actress got married to actor John Stamos on Saturday.
They didn't reconnect until years later, when her roommate appeared on an episode of "Fuller House" and she dropped by to watch from the audience.
According to Entertainment Tonight, the pregnant bride looked handsome in a white strapless gown with a full tulle skirt.
The pregnant McHugh reported the burglary from her Beverly Hills Hotel room Friday night, police said.
Sources tell TMZ the jewels were on loan from the Neil Lane collection.
Then in December, the couple announced they were expecting their first child together.
Stamos, 54, stars in Netflix's Fuller House and spent part of past year with The Beach Boys as a drummer. "I've been practicing for a long time", Stamos joked.
"I walked in, I went, 'Hey, are you stalking me?' She was like, 'No...' That's why I love her".
"I hope [to have kids]", Stamos told ET in November, before McHugh's pregnancy announcement. "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".
