Katy Perry's

Interrupting her busy schedule for a nice meal, Katy Perry arrived at Nobu in London, England on Friday (September 27).

The “Roar” singer looked adorable in a fuzzy short-sleeved white sweater, black and white patterned miniskirt, knee-high socks, and saddle shoes as she headed inside.

Recently, the 28-year-old chart-topper appeared on the cover of Billboard magazine where she spoke about her upcoming album, PRISM.

Described as her favorite song on the record, Katy confirmed that “Unconditionally” will be her next single. She told MTV, “It”s a love song and it”s different from “Roar” – It”s not eight-notey. And I think it”s a universal love song that everyone”s going to be able to relate to no matter the age, no matter male or female. It”s my favorite song off the record.”
