Austin has been leaving extremely flirty messages on Camila's Instagram.
On a HOT AF pic of Camila at the American Music Awards yesterday, Austin 'liked' the pic as well as posting two fire emojis.
Now we all know what that means.
At the time of their split, Camila only had nice things to say about Austin.
"I don’t regret anything," she said. "It was my first kiss, my first love. It’s important to learn about liking somebody and being swept away, but it wasn’t meant to be."
Watch out Matthew!!
