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 (14.02.13) but they reportedly have no plans to get engaged anytime soon and the ring was simply a thoughtful gift.

Katy Perry's parents are very ''comfortable'' with John Mayer.

The brunette beauty and her singer boyfriend were joined by her mother and father, Mary and Keith Hudson, for dinner at Mr. Chow in Beverly Hills after the Grammy Awards on February 10 and the quartet seemed to enjoy one another's company.

Katy Perry was all over John Mayer at a pre-Grammys bash.

The 'Firework' singer - who split from British comedian Russell Brand in December 2011 after 14 months of marriage - was spotted being extremely affectionate with the 'Half of my Heart' singer, slipping her hand under his tuxedo jacket to rub his lower back at Clive Davis's Gala & Salute to Industry Icons in Beverly Hills on Saturday night (09.02.13).

Russell Brand finds yoga ''trippy''.

The British comic - who has battled drug and sex addiction but been clean for nine years - starts every day with transcendental meditation then Kundalini yoga and finds the techniques ''overwhelming''.

Russell Brand has ''let go'' of the urge to protect Katy Perry.

The couple split in December 2011 after 14 months of marriage and though the British comic thinks his former spouse is ''perfect'', he doesn't want to interfere with her new relationship with infamous womaniser John Mayer.

Russell Brand has invited Demi Moore to visit India with him.

The British comic thinks his friend - who endured a stint in rehab last year following her split from husband Ashton Kutcher - would benefit from joining a group trip to The Ananda Spa in the Himalayas, a yoga retreat which promises to ''cleanse the soul and heal internally'' and offers meditation classes and healthy eating.
