Katy Perry, who campaigned for President Obama wearing both a “Forward” logo dress and a dress that looked like a completed ballot, performed at the invitation-only Children’s Concert hosted by Michelle Obama and Jill Biden wearing something that looked a lot like Wonder Woman’s costume.
Lady Gaga is rumored to be performing for White House staffers at a ball on Tuesday.
