"[That's] life on the road when you're a superhero," Ruffalo explained of his Instagram pic, which showed Hemsworth, Tom Hiddleston, and Ragnarok director Taika Waititi spooning mid-flight. "You gotta grab it where you can get it, you know?"

"There's no shortage of love in this cast," Hemsworth added. "What there is a shortage of is space on the place, so, you know, if you're doing 24-hour days and traveling the world, you kind of get it where you can... sleep, that is. And cuddles."

"I don't mind [if I'm the cuddler or cuddlee]," he revealed.

"It's beautiful both ways, really," Ruffalo chimed in. "The world needs more cuddles."

While the Avengers co-stars clearly can't get enough of each other, their characters appear to be at odds in the upcoming Thor: Ragnarok.

"After Avengers, what was it, we're up to now three, Hulk went missing, didn't he? And Thor's kind of been out there on the road himself, and traveling the universe, and he comes across an old friend from work," Hemsworth said of the new movie.

"[Hulk] may or may not respond with the same kind of, you know, excitement and passion as [Thor] has," he continued, before addressing Ruffalo directly. "Why weren't you happy to see me? I was rapped to see you!"

"I think he's really torn at that point," Ruffalo hypothesized. "He's torn."
