Katy Perry posed, twirled her hair, laughed uproariously and even appeared to try to give the Vulcan peace sign from “Star Trek” as she posed for photos yesterday (Nov. 15) in Cologne, Germany. She’s currently touring to support her new album Prism.

Perry, who turned 29 last month, wore a shiny metallic outfit that seemed to match her buoyant mood.

It may have been because she was just coming off her win the previous weekend at the MTV European Music Awards for Best Female Act.

She wore a biker-style jacket and a pleated miniskirt made of the same material. The design was by Unif, a brand known for its ’90s fashion-inspired collection of tees, dresses, pants, shoes and accessories.

She accessorized with silver cross earrings and sky-high, open-toed heels also by Unif. She wore her hair in a bobby-soxer ponytail tied with a jeweled scrunchie.

A day earlier, Katy released a teaser video (see below) for her new music video for her song “Unconditionally.” The song is a homage to unconditional love.

Her stay in Cologne also included an interview at radio station 1 Live.
