New couple alert?

Bella Thorne and Charlie Puth may be Hollywood’s latest pair. Over the weekend, pictures surfaced of the two spending the day together at a Miami beach.

According to an insider, things continued to heat up between the two after their sunny beach date. The singer, 25, had serenaded the 19-year-old actress at the 2016 iHeartRadio Jingle Ball later that night after the pair posed for a sweet red carpet photo together.

“Charlie said that they were just friends, but during his second song, he was singing to her on stage — she was off side-stage,” a source who was backstage at the event tells PEOPLE.

Thorne was recently linked to Teen Wolf star Tyler Posey and the two weren’t shy about sharing intimate photos of their relationship on social media. The former Disney star uploaded a photo on Instagram in October of her straddling Posey in a pool on a float with the caption, “Pool vibes with my baby.”

Puth was previously linked to “Marvin Gaye” duet partner Meghan Trainor after the two made out onstage at the 2015 American Music Awards — but the singer quickly cleared the air. “Before it begins … we are just friends,” he said at the time.
