"Shut Up" is the second single released by Kelly Osbourne. It is from her debut album Shut Up. It reached the top 20 of some European charts, but only reached #34 in Australia. It was not as successful as her debut single, a cover of "Papa Don't Preach" by Madonna.
Reportedly, Kelly wrote the song about her brother Jack Osbourne, and his annoyance of her when she was a child.
