and Chris Evans
are the friendliest exes ever -- assuming they're still exes, that is!
The pair, who broke up in January after less than a year of dating, have fans speculating that they're back together, following a series of clues on social media.
Rumors first started to swirl as the two were spotted hanging out in Atlanta, Georgia, last month -- before exchanging flirty messages on Twitter.
"How's your handwriting? Can you write me a note?" Evans tweeted at Slate. "Let's cut class!"
"This is terrifying and exhilarating. Meet me behind the gym after science. I have shark bites," she replied.
Then, on Tuesday, Evans posted a seemingly innocent video of his dog, Dodger, singing along to his toy -- with what sounds like Slate giggling in the background. The Avengers
star posted a similar clip on Thursday, but this time Slate appeared to give her commentary.
