Yup, she has replaced Britney as America's "relatable" but sexy popstar. It all started when Max & Luke gave her all the hits, leaving Britney unable to score a solo top 10 anymore (Criminal, Ooh LaLa, Work Bitch).
Just cuz it's not generic or predictable doesn't make it good. It was stupid and embarrassing.
Wasn't it for a radio interview? Not like it matters what's on her face. She was obviously wearing it in celebration of the start of pre-orders of Arkham Origins.
