Katy Perry flashes heart shaped engagement ring on Valentine's date with John Mayer

London, Feb 16 (ANI): Katy Perry left Vincenti in Brentwood on Valentine's Day with her beau John Mayer sporting a ruby ring in the shape of a heart on her left hand.

It's been a busy week for the pair, who were also spotted enjoying a pre-Valentine's Day dinner on Tuesday night at Katsuya in Brentwood, the Daily Mail reported.

The holiday marks John and Katy's first Valentine's together, but seems to be setting a precedent for a lot more to come.

According to reports, the couple, who have been dating on and off since Katy's divorce from Russell Brand, are going from strength to strength - especially after John hit it off with Katy's parents. (ANI)
