Katy Perry shrugs off engagement rumours as she leaves her diamond ring at home for outing with Orlando Bloom

KATY Perry shrugged off rumours of an engagement as she stepped out with boyfriend Orlando Bloom at the UNICEF Snowflake Ball.

The singer looked radiant as she walked the blue carpet for the event in a floaty full-length ball gown.

And there was no sign of the sparkler on her wedding ring finger which on Monday night fuelled rumours Katy was planning to tie the knot with her British beau.

Wearing her dark hair slicked back, the focus was instead on the 32-year-old's ethereal outfit.

With delicate corsage pieces around her cleavage, the dress nipped in at the waist before the pleated material flowed to the floor.

The Roar hitmaker was closely followed by her actor boyfriend Orlando, who looked dapper in a dark blue tuxedo suit.

But Orlando, 39, made sure the focus remained on his girlfriend as she was presented with the Audrey Hepburn Humanitarian Award at the New York event.

Former presidential candidate Hillary Clinton handed Katy the prestigious award at the Cipriani Wall Street fundraiser.

Katy and Orlando recently proved their relationship was still going strong as they celebrated Thanksgiving together, despite rumours of a break-up.
