Apparently, the new couple recently watched Disney's Big Hero 6 (solid new couple film) and the nickname originated there.
"The big guy was [named] Baymax. We watched that two weeks ago … and I was like, 'I love the name Baymax,'" Jordin said. "[Sage] was like, 'I'm your bae to the max,' and I was like, 'That's your nickname!'
It seems like they are really hitting it off!
"We're having fun. He's a really good guy," admitted Jordin. "The pictures speak for themselves … I don't just kiss people!"
