The Grammys might have introduced a dress code banning pop stars from showing too much flesh at this year's ceremony, but that didn't stop Katy Perry and Rihanna from working it on the red carpet.
Katy Perry And John Mayer Engaged Over Valentine's Day?
The 'I Kissed A Girl' singer was pictured wearing a heart-shaped ring this week.
Katy Perry has sparked rumours she's got engaged to her boyfriend John Mayer after she was pictured out on Valentines Day wearing a heart-shaped ring.
The 'Part Of Me' singer started dating the blues-pop musician last summer – shortly after she finalised her divorce from comedian Russell Brand.
She was also rumoured to have been wearing a similar ring at last weekend's Grammy Awards 2013 ceremony.
John recently admitted the relationship felt like something he'd never experience before.
"I don't feel like I'm in a celebrity relationship," he said. "For the first time in my life I don't feel like I'm in a celebrity relationship.

"I know it is high profile. It's hard to explain... For me it feels like something that's very human."
Meanwhile, the 'Hot N Cold' singer's ex Rusell brand recently weighed in on the couple's romance calling John a "worse womanizer" than himself and praised his former wife as being "perfect".
