On Saturday — her 25th birthday, the Grammy winner tied the knot to actor Daryl Sabara.
PEOPLE confirmed they said "I do" in front of 100 close friends and family in an intimate backyard ceremony at their L.A. home.
“It’s the beginning of an awesome, whole new life,” says Meghan.
“I got way more than I ever wished for.”
“I’m the luckiest guy in the world,” adds Spy Kids star Daryl, 26.
To walk down the aisle, the bride wore an elegant Berta gown, Badgley Mischka heels and Norman Silverman jewels.
Then for the reception, where guests noshed on an assortment of comfort foods, Trainor slipped into a lace suit by Rita Vinieris and Aldo sneakers to get the party started.
As for what the newlyweds are looking forward to most in marriage?
“Just rockin’ them rings!” says Trainor, who exchanged bands with Sabara after reciting hand-written vows during the ceremony, which was coordinated by the wedding planners at Sacks Productions. “I’m really excited to say ‘hubby’ and ‘husband.'”
Indeed, “I’m no longer the ‘future hubby’ — I get to just be the hubby, which I’m excited about!” adds Sabara, alluding to Trainor’s 2015 hit single “Dear Future Husband.”
