Although neither have confirmed the dating rumours, they also haven't denied them, so... we've come to our own conclusions.
Now, however, fans are certain that Hailey has broken Cameron's heart, due to some shady AF tweets.
Cam started tweeting early yesterday morning, writing: "Heartless, but you made me that..."
He then added: "trusting people really sucks sometimes," and "I don't want to rush into if it's too soon."
Hailey joined in on the cryptic tweets, starting off with: "Does anybody really LIKE confrontation tho ."
Fans then started subtweeting them both a bazillion questions about their relationship, feeling heartbroken for Cameron in the process.
Neither Cameron or Hailey directly tweeted one another, so it's all speculation at this point. But, you gotta admit it does seem a little coincidental...
