The 32-year-old actress has confessed she quietly dated her 'Scott Pilgrim Vs. the World' co-star for "a long time" and things were so serious between her and the 28-year-old actor, they considered tying the knot.

Speaking to RuPaul and Michelle Visage on their 'What's the Tee?' podcast, Aubrey said: "I dated him for a long time. We drove across the country after we shot that movie and almost got married in Vegas."

Ru then asked if the relationship was a result of spending so much time together on set.

Aubrey replied: "Oh, like animals in captivity? Everyone just wants to fuck each other?"

But she insisted that wasn't the case and the actor is still "very special" to her.

She added: "We love each other. We're still really good friends. He's just a weird little freak and we speak the same language. He's one of the funniest people I know."

The former 'Parks and Recreation' star recently revealed she is bisexual.

She said: "I know I have an androgynous thing going on, and there's something masculine about my energy.

"Girls are into me--that's no secret. Hey, I'm into them too. I fall in love with girls and guys. I can't help it."

And the 'Mike and Dave Need Wedding Dates' star understands her own LGBT fanbase because she feels like an "older gay man" at heart.

She added: "I feel like I operate in an old-school way that only gays truly understand. So for me it's the ultimate compliment. My tastes are like an older gay man's, and I think that's who I really am.

"Like, I grew up obsessed with Judy Garland, and I was also obsessed with how much she meant to her following."

Aubre says her family have always been supportive of one another's sexualities so there has never seemed anything different or unusual about same-sex relationships to her.

She said: "I have a gay aunt and a gay uncle, and I grew up thinking that everyone had a gay aunt or uncle.

"My younger sister is a lesbian, so it's just in my blood, I guess. She came out to me when she was 17 or 18, and for, like, a millisecond I was surprised. Then I replayed our entire life in my mind, and I was like, 'Of course! Of course I know that!' She's my best friend."
