Katy Perry officially debuted as Mrs. Brand last night to a packed house in NYC. Performing a free concert in honor of the debut of the Windows Phone 7 at Roseland Ballroom, Katy told the crowd, "I love New York. I do. I have an apartment here!" She also made a joke about owning "one of those t-shirts."
Katy dedicated her hit "Ur So Gay" to the "old me." She also performed such Katy classics as "California Girls," "I Kissed A Girl" and "Hot n Cold" and new songs like "Last Friday Night" and "Teenage Dream."
After the concert Katy talked about how her new marriage is doing! When asked she said, "It's beautiful. It feels complete."
Katy also loved meeting her fans during a Windows Phone 7 meet and greet. She complimented their clothing and loved the gaggles of girls coming up to her to gush their love. Katy looked amazing wearing a purple latex dress adorned with cupcakes.
