BREAKING BUBBLINE NEWS! At an LA book signing for The Adventure Time Encyclopedia, the voice of Marceline The Vampire Queen, Olivia Olsen, confirmed what many fans already suspected to be true...
... that at some point in time Princess Bubblegum and Marceline TOTALLY WERE A COUPLE.
Olson answered a fan's question (cut off in the video) concerning Bubbline, referencing a conversation she had with creator Pendleton Ward.
"And he said, 'oh, you know they dated right?'"
I was at the studio on Tuesday and Pen was actually there because he was recording for Lumpy Space Princess and I wanted to ask him a lot of questions, because he's trying to write the book and stuff so I wanted to pick Pen's brain a little bit. And he says, 'Oh, you know they dated, right?' And I said, 'Wellll, that's what I figured from all the creepy fan art.' [cheers]
