Fans have been chalking up Jhené Aiko & Big Sean’s close relationship as of late to their status as the newly-formed duo TWENTY88. But a recent kiss on stage now has onlookers thinking their union is more than just musical.

It was just this past March that producer Dot Da Genius announced his marriage to Aiko on Instagram, posting a picture of their ring exchange with the caption: “Happy Birthday to my gorgeous wife. Happy to be on this quest with you.”

But that post has since been deleted (see the original above), as have all the photos he once shared of her.

Now, it’s believed that Aiko and Big Sean are more than just platonic partners. Rumors first began to surface when designer and stylist Ade Samuel posted a photo of the duo backstage at The Late Late Show with James Corden, Aiko on Sean’s lap.

And a glance at either one of the artist’s accounts will show that their photos together have gone from promotional to personal.

But the final hint at their relationship came this past weekend when the two performed at Power 106’s Powerhouse concert together, Big Sean wrapping his arms around his waist and kissing her cheek on stage.

Is this a publicity stunt or the real thing?
