‘Finally it feels like Christmas’: Katy Perry wears festive black velvet off the shoulder dress and fishnet tights as she watches The Nutcracker at Sydney’s Opera House

She’s used to spending Christmas in the chilly US winter. 

And as she enjoys the run up to the festive season in Sydney’s summertime, Katy Perry is starting to get into the spirit.

The pop superstar, who is currently on her Prismatic World Tour Down Under, left The Sydney Opera House after watching The Nutcracker Ballet on Thursday night looking very glamorous.

According to sources, Katy later headed out to the Opera bar which reopened on Thursday night after short closure.

The 30-year-old raven haired star looked elegant as she was seen walking up the stairs of the famous Opera House in the outfit, which she teamed with a gold belt and pair of black heels with fishnet stockings.

Earlier on in the day, Katy was seen doing some last minute Christmas shopping in Sydney’s trendy Surry Hills.

Although her hair was in the same ponytail style, Katy has looked notably dressed down in comparison to her evening attire.

As she had walked along with only a pair of black Wayfarers to hide her identity, the Fireworks singer looked like any other Sydneysider as she wore a black animal print dress with a big brown cardigan.

Katy, who has been in Australia for the last month, will perform her last show on this side of the world in New Zealand on December 20 before returning home to the US just before Christmas.

As well as playing two more Sydney gigs on Friday and Saturday night she will play her last show in Australia in Brisbane on Monday.
