The photo shows Austin and Camila leaning in close together, with broad smiles on their faces. Camila is even playfully sticking out her tongue a bit.
"Always good to see @camila_cabello, " he captioned the photo, complete with a smiley face.
Austin also retweeted a supportive tweet that Camila sent him on Monday, Feb. 24.
"sick job tonight @austinmahone you slaaaaaayed, break a leg on the rest of your tour!!!!! but not literally. that would be unfortunate," she wrote.
Of course, the two could just be platonic friends who enjoy each other's company. Austin denied late last year that they were dating.
"So, you know, she's a really, really cool girl, very nice, but we're not dating," he said at the time.
With how well they seem to get along, perhaps one day fans will be treated to, if not a love story, a duet?
Do you think Austin Mahone and Camila Cabello would make a cute couple?
