Is the BubblegumxMarceline claim a lie?

ORIGINAL POST:

A little while ago it's been confirmed that princess Bubblegum and Marceline from Adventure Time were in a relationship once.

While I can't say that canon homosexuality impressed me, as it's an easy way of gaining a fanbase and being called "clever", I should still give the creators of the show credit for making a bold move in a shitty society like ours.
Still, it's too bad that this revelation was totally pointless to announce, as it's been said it will never be portrayed in the show or comics, for obvious reasons. It basically has as much importance in the story and to the characters as Dumbledore's confirmed homosexuality in the Harry Potter series. So, while we're giving out random personal information, why not mention all the cartoon characters who are heterosexual in the future? Apparently we all want to know this more than anything else.

Anyway, this pairing itself is not the reason I started this article. I started it for those cheering fans who now yell "We told you so" and "Fuck yeah, the rumors are true".

You mean the same rumor that revolves around every single damn cartoon character in existence? 

The claim that everything and everyone is gay for everything and everyone? 

Not because it might be true, but just because it looks so "kawaii"?

Bubblegum and Marceline were guessed to be gay for each other, because Bubblegum cherished a t-shirt that Marceline once gave her, or something like that, and I can't consider a scene like that to be solid proof of their sexual feelings for each other. It just as wel could've been proof of a close friendship. So, excuse me for not buying it right away.
Let's not pretend that Bubblegum and Marceline's case is nothing like all the other homosexual claims concerning fictional characters; fans were again just spouting bullshit, and this time it worked out.

But well, Bubblegum and Marceline, rock on.
...
Except, no, because your relationship is over and will never have a solid mention ever.
Never mind, you two are pointless.
Back to Finn and Flame princess we go.


UPDATE 06-09-2014:

This article was once named "The BubblegumxMarceline confirmation", but right after I felt motivated and polite enough to draw and upload a drawing to support this pairing on Deviantart, even though I gender-swapped the characters, it didn't take long for someone to come along and tell me it was a joke from the voice actor who made the claim.
The actor's original Twitter message confirming this is gone, as she apparently got butchered and cursed to Hell by the fangirls, but it said:

"I like to make things up at panels. Ya'll take my stories way too seriously..."

What the fork? She made this claim on a Q&A, for Pete's sake, you go there to ask questions and get them answered. If you have to depend on the kindness of the people sitting on stage to answer your questions truthfully, why even bother arranging/attending these events.
I can go on the internet and ask a random person about a show if I want to get bullshitted.

While I portayed my dislike for slash fangirls on this same blog, I feel urged to take their side on this. This is a strange prank to be pulling on people who thought they could embrace two bisexual (you're not really homosexual if you date the opposite gender later on) characters in a show that isn't South Park or Ren & Stimpy.
Even so, that is their view, not mine. I'm not bothered because the pairing could've been that "revolutionary first stone in animation" or because I wanted it so badly, because I don't. I never considered Bubblegum and Marceline to make a cute or logical pair, and I wasn't expecting or wishing for a confirmation like this.

No, what bothers me is that someone, who has the knowledge, lied about something people obviously care about. It's a sad thing that a fictional character's sexual orientation is so important to people, but it simply is.
Then again, maybe it isn't that aspect that people wanted to know. Perhaps people just wanted to know that Bubblegum and Marceline once loved each other.

It's hard to respect a person who is allowed to speak as an authority and then yells "JK!" whenever it suits them. She could've told fans she was shitting them when she was still at the Q&A, instead of laughing at them for believing her the next day. Do you value your fans this little?

But I'll be honest that the fangirls haven't been that polite, either. I already described how they responded, they're fangirls.

Even so, when reading the comments responding to the Tweet at Reddit, I got doubts about the whole situation. Was this really just a pointless joke, or did she get in trouble for revealing the truth. We know there are alot of God-fearing parents who would go beserk over a claim like this one, and that would mean the end of Adventure Time.
Then again, we shouldn't exclude the possibility that this voice actor is just a bitch.
