Selena Gomez and Justin Bieber have been tight-lipped about their relationship since reuniting last fall. Though the PDA pics and vacation photos give it all away, both stars have refrained from mentioning each other on social media or in interviews. That changed this evening, however, when Gomez shared a subtle but sweet post dedicated to Bieber, in honor of his birthday today.

"March 1, 1994 someone I know that happens to be super cool was born. Boom," she captioned a picture of herself smiling, with what looks like a Polaroid of Bieber on her head.

She didn't tag him or write out his name, but she didn't need to for fans to realize who she was talking about. At the time of writing, it doesn't look like Bieber has liked or commented on the photo just yet.

A fan account, Selena Gomez News, pointed out that the couple also appears to be kissing the photo she shared.

This marks Selena's first photo dedicated to her pop star beau since the two reconnected at the end of October. She took her time when posting about her last relationship, too. She didn't share a pic with The Weeknd until they attended Coachella together, a few months after rumors first speculated that they were an item. (Her photos with the Starboy singer from the Met Gala and a dinner date are still on her page, by the way.)

Gomez's photo arrives a week after she and Bieber traveled to Jamaica together to attend his dad's wedding. While vacationing in the Caribbean, they were seen enjoying their time together and packing on the PDA, sending Jelena fans into a frenzy.
