Katy Perry eats pizza to calm her nerves.
The 28-year-old singer's lead single Roar from her fifth studio album Prism reached stores last month and she premiered the accompanying music video this week.
With all the excitement going on, Katy has developed quite a large appetite and since she is visiting the Big Apple, she knows exactly what she needs to calm down.
"The only way to end the longest day ever is to stuff my hole with a slice of NYC's finest! #SEEYAINTIMESSQUARETOMORROW," she tweeted.
Gracious Katy even offered to feed her fans.
"Yeah girl, you want me to bring you a slice?" she said in response to one follower who seconded her opinion about New York City firing up the best pizzas.
Katy is currently in New York City for Mercedes-Benz Fashion Week and she also told fans on Twitter to expect a big surprise from her Friday morning, writing: "...TOMORROW morning @GMA! I've got a big announcement! And you might want to keep an eye on that Jumbotron! Meet me in Times Square..."
Katy's new music video for Roar sees her swinging around a jungle, much like Tarzan.
She got to work with exotic animals while filming, but she had a clear favourite co-star.
"Suzy the elephant cause she wouldn't stop eating everything!" she wrote on the micro-blogging site.
Katy's new album Prism will reach listeners next month.
