Grammy winner Meghan Trainor is engaged to "the kid from 'Spy Kids'" -- actor Daryl Sabara -- but funnily enough, she doesn't remember what her now-fiancé said during the proposal.

As a guest on "The Tonight Show" on Wednesday, Trainor gave host Jimmy Fallon the details of Sabara's recent proposal, calling it "perfect." She shared that her fiancé managed to surprise her on her 24th birthday during a visit to a zoo lights show in Palm Springs. He popped the question with her whole family there, and Trainor was so excited that she "blacked out" and had "a quick panic attack."

Her retelling of the story was adorable. We love that not only does she, herself, refer to her future husband as "the kid from 'Spy Kids,'" but she also gushed to Fallon and the crowd, telling them, "I'm in love!"

Watch Trainor tell the story below, starting at 1:24.

"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET/PT on NBC.
