Katy Perry.

Katy Perry's concert @ Globen, Stockholm.
She's not my favorite artist or Otto's either. But when Otto turned 30, I gave him tickets to ths concert. He had been talking about Katy Perry's coming concert in Finland (just kidding of buying tickets to there). But in the Finlands concert was not ticket's in good place's left so I decided to buy ticket's to this concert, even he had been just kidding but he had been talking about it "lot". It was also the last concert of the Prismatic Tour in Europe! =)
The concert was great! We both liked it alot.
