Big Sean recently dished on his lady love in an interview withComplex magazine, explaining that they were legitimate friends first before taking their romance to the next level.

"I'd never done that," he admitted. "Usually you meet a girl and then start dating. We always saw each other in the studio, and we'd talk about songs we were working on. It was cool to have a girl that I could talk to about my problems."

"It's not some fake-ass, inauthentic s*it when I say we were friends," he stressed. "This is something special and I appreciate every moment of it."
