Katy Perry to sing for Barack Obama

OHMYGOSSIP — Katy Perry is set to sing for President Barack Obama at the 30 Days to Victory concert. The singer will join several artists, who’ve yet to be announced, for the fundraising concert at the Nokia Theatre in LA on Oct. 7.

General admission is $250 a person, but supporters under age 40 can purchase a ticket for $44.

Katy has always been an avid supporter of the president, who is seeking his second term.

“I was really happy,” she said about the president when he came out in support of marriage equality.

“I probably went down to West Hollywood and had a shot. I came from a different mind-set growing up, and my mind has changed.”
