Pop star Katy Perry has given the impression that there could be a new man in her life based on something she wrote on social media.

Katy Perry & Robert Pattinson Relationship Rumors?

On Wednesday, the "Birthday" singer took to Twitter to talk about her co-worker Ferras who she worked with on the song "Legends Never Die." He happened to give an interview with Idolator on his work with the pop star where Perry added something in her tweet that seemed a little detailed.

ALIENS Check out my boo @ferras interview on @idolator," she wrote, adding in a link as well as emojis of alien heads.

Did Katy Perry Hear Bad Stories About Taylor Swift?

In Ferras's interview, he mentioned how he and Perry decided to work together, which came about when she decided to have a meeting.

"We were in Paris at fashion week and Katy asked if I wanted to come downstairs to the little, I guess, restaurant, in the hotel and she wanted to have a meeting," Ferras said. "Katy's kind of like our mom of our group so when Katy wants to have a meeting, everybody's kind of like, 'Alright, what's going on?'"

Even though Perry referred to her co-star as her "boo," odds are likely that she meant it in a playful way since Ferras was asked in his interview if it's hard being an "out artist." He said that being an artist who's different from what's "politically correct" is becoming less of an issue these days, and that gay artists can be more expressive when it comes to music.
