Katy Perry, John Mayer to marry this summer?

London: Pop star Katy Perry is reportedly planning to marry her musician boyfriend John Mayer in June.

The 'Who You Love' hitmakers, who have been dating around 18 months, sparked speculation they were engaged when 'Prism' singer stepped out on Valentine's Day wearing a ring on her engagement finger, reported Daily Mirror.

"They'd love a June wedding. They want to get married at the San Ysidro Ranch in Katy's home town of Santa Barbara," a source said.

Perry, 29, was previously married to comedian Russell Brand.
