Katy Perry and John Mayer 'split' after two years
The pair, who are rumoured to have been engaged, split in the last few days, according to E! Online.
The US entertainment news site is running an exclusive story about their break-up.
Earlier this week, engagement rumours followed the couple once again when Perry stepped on to the red carpet wearing a diamond sparkler, and it was even reported that her pastor father would officiate the ceremony.
The high profile couple have had no qualms about speaking publicly of their love and even recorded a duet, Who You Love, together last year.
Katy previously gushed over her loving relationship with John.
She acknowledged her new beau fulfills her needs and being in love with another musician adds another level of intimacy.
“There’s a lot more understanding of context and that’s very nice,” she explained to Extra around the time of the song’s release.
“And also you get to share music! The dance parties are much more fun.”
Katy was officially divorced from British comedian Russell Brand in 2012. Should she wed John, this would be her second marriage and his first.
