Katy Perry working with Taylor Swift producers
Katy Perry is working with Taylor Swift producers Max Martin and Shellback on her new album.
The 'Roar' hitmaker and 'Shake It Off' singer may be bitter rivals, but that hasn't stopped the 31-year-old pop beauty working with the masterminds behind Taylor's 'We Are Never Ever Getting Back Together' for her follow-up to 2013's 'Prism'.
Taking to Twitter, Katy - who has worked with Max since her debut LP 'One Of The Boys' - wrote: "Ok back to the studio for me. 2017 is gonna tight af ...MAKE LYRICS GREAT AGAIN ! cc Max Martin & Shellback (sic)"
Katy - who is dating actor Orlando Bloom - recently admitted she was working on a fifth album but is "not rushing" the record.
She said: "I'm just having a lot of fun, but experimenting and trying different producers, and different collaborators, and different styles."
Earlier this month, Katy admitted in a Twitter Q&A that she would be prepared to end her feud with Taylor, 26, if the 'Blank Space' star apologises to her.
When asked if she would work with the blonde stunner, Katy replied: "If she says sorry, sure!"
The pair have had an ongoing feud ever since the 26-year-old star claimed the 'Unconditionally' singer nicked three of her backing dancers from her 'RED Tour' in 2012.
And Katy recently teased that she plans on going on tour in 2017.
She said she will play at least one concert in 2017 after revealing such plans when responding to a Twitter troll who hit out at her career and standalone track 'Rise', claiming it was a "flop".
In a Q&A with fans, one tweeter wrote to Katy: "Rise flopped and your career is over."
The raven-haired beauty responded: "See you at my show 2K17."
