Selena Gomez's new album A Day Without Rain has a big surprise: Katy Perry as a contributing singer!

Katy Perry will be on Selena's new album. Selena said in an interview that Katy will sing on A Day Without Rain, where we will hear the two harmonizing together.

We don't know much more about the project. We don't even know what the name of the new song is. What we do know is that Selena said she had a lot of fun working on the song with Katy.

We can't wait to hear what the two of them have come up with!
