Rihanna made her long-awaited return to the stage at the Super Bowl with a career-spanning medley of pop bangers, but it was her baby bump that dominated the conversation.

Representatives for the singer confirmed the speculation to trade magazines Rolling Stone and The Hollywood Reporter: Rihanna is pregnant with her second child.
