The "Birthday" singer was spotted performing a reggae song with rumored boyfriend Diplo in a studio as Katy Perry dating rumors with "The Rover" actor Robert Pattinson came into halt because of his ex-girlfriend Kristen Stewart.

According to Music Times, the "Birthday" singer was seen working with rumored boyfriend DJ Diplo's group Majoy Lazer in a recording studio for some reggae music. The rumored couple was also with Walshy Fire and reggae artist Jesse Royal.

The report said that it was "odd seeing one of the world's biggest pop star get her reggae on."

However, it was still not confirmed if the reggae song will be part of her new album or if she will be collaborating with her rumored boyfriend Diplo's group in their latest release.

Katy Perry dating Diplo rumors circulated after the two were spotted flirting with each other at Coachella in April.

Aside from Katy Perry dating DJ Diplo, the pop singer also hooked-up with "The Rover" actor Robert Pattinson.

The news of Katy Perry dating Robert Pattinson started after party of "The Rover" when they were seen being intimate with each other.

But according to Celebrity Laundry, their romance stopped as "The Rover" and "Twilight" actor have already reunited with his ex-girlfriend and co-star Kristen Stewart.

Reports revealed that "The Rover" actor Robert Pattinson always stays at his ex-girlfriend's pad in Los Angeles when he is in town for the promotion of his latest movie.

The rumor that the two are back in each other's arms seemed to get the "Roar" and "Birthday" singer jealous, according to Celebrity Laundry.

"Rob and Kristen getting back together is wonderful for their fans but is no doubt going to create a little jealousy in Katy," the report said.

It has been reported that Katy Perry and Robert Pattinson were friends for a long time and that "The Rover" actor wanted the friendship to be taken to the next level. However, the singer seemed to be hesitant with the relationship as she was also dating other guys.
