The real Katy Perry is an outspoken supporter of President Obama. The “California Girls” singer performed at a Las Vegas fundraiser for Obama’s reelection campaign last week — her second such event in less than a month.

Ryan’s sons, Charlie, 9, and Sam, 7, dressed as “spooky goblins” as they gathered candy in their Wisconsin neighborhood, according to The Associated Press.
