Riteish is mighty upset with Shah Rukh Khan

Shah Rukh Khan was good friends with Riteish Deshmukh and Arjun Rampal. While his friendship with Arjun is still intact, Riteish seems to have left with a bitter taste in his mouth.
The reason behind the rift seems to be Shah Rukh choosing Arjun over Riteish to play the villain in Ra.One in spite of Riteish being the first choice.
