John gives Katy his heart (ring)

John Mayer gave Katy Perry a heart-shaped red ruby ring for Valentine's Day.

The 28-year-old 'Part of Me' singer - who split from Russell Brand in December 2011 after 14 months of marriage - was spotted wearing the unique ring on her engagement finger for a romantic dinner at Vincenti in Brentwood, California with her 35-year-old boyfriend on Thursday night but they reportedly have no plans to get engaged anytime soon and the ring was simply a thoughtful gift.
