London: Robert Pattinson`s final bust-up with Kristen Stewart was sparked by his date with singer Katy Perry, it has been revealed.
According to a close pal, the 27-year-old actor hooked up with Perry for a night out in New York two weeks before he split from Stewart, the Daily Star reported.
Actress Bella Rapone, a friend of the singer, said, "She and Rob started off in the Bowery Ballroom, where they watched a gig by the indie band Daughter with a whole bunch of people, mainly pals of hers.
Then they took off with a smaller group for a much more intimate venue, The Spot at the Trump SoHo Hotel.
She said that it was obvious there was chemistry between them, and that they`ve always liked each other.
Rapone said Pattinson is "outraged" at the way Perry was treated by Brand and John Mayer, who she dumped in March for cheating on her.
