Honey baby love

I'm writing a book and suddenly, the hero calls the heroine baby. Huh. Didn't see that coming. I thought he'd be more of a "honey" type, but no. At least it's not sweetie-umpkins, right? Which brings me to the question of the day. What does/did your significant other call you? And if that doesn't apply, what do you WISH a significant other would call you?
