Charlie Puth and Sabrina Carpenter have announced an upcoming song collab by kissing on TikTok and fans are losing their minds.

After cryptically tweeting that “the start of something special comes tonight,” Charlie Puth posted a TikTok that both confused and excited fans.

In what appears to be a teaser for what will be a juicy collaboration between himself and Sabrina Carpenter, the pair, who are not romantically linked, kiss.

Charlie Puth and Sabrina Carpenter tease new song

In the promo video for their upcoming single’s video, Carpenter and Puth are playing a game of Operation in a candlelit room. Carpenter successfully pries out the heart and holds it up to Puth, who says, “I always knew you had a tiny, tiny heart.”

At that point, piano music begins to play, and the clip cuts out just as the Disney Channel alum and See You Again singer kiss.

The TikTok’s caption tags Sabrina and reads “3.31,” the date fans will be able to hear the full track.
