"No one expressed how they liked my body out loud in the bedroom until I met Daryl," she confesses. "He is obsessed with it -- every inch. And that has improved my confidence more than even 'Bass' did."

The couple, who have been dating since last fall, has had romantic chemistry ever since their first date, Trainor reveals in the interview.

"He was the best kisser ever," she gushes about their first kiss, which happened at a bowling alley. "I know I'm really good at kissing, but I was shocked when he was. [...] I told my security to step outside 'cause I didn't want to be watched. LOL."

The interview marks the first time Trainor has opened up about her relationship, which started during her time away from the spotlight as she recovered from vocal surgery. And it sounds like she's very serious about it.

"I wrote six songs on the road about him in front of his face," she reveals. "One is called 'Marry Me.'"

Could we be gearing up for a Meghan Trainor and Daryl Sabara wedding?! Only time will tell.
