Katy Perry not happy with Russell Brand’s Super Bowl good luck tweet

Katy is reportedly unhappy that Russell chose to "involve himself" on the biggest night of her career.

Katy Perry was offended by Russell Brand's good luck tweet before her Super Bowl performance on Sunday.

The 39-year-old comedian - who was married to the pop star from October 2010 until July 2012 - wished his ex-wife well before her half-time performance at the game between the New England Patriots and the Seattle Seahawks in Glendale, Arizona.
