-: A source present at Katrina's birthday bash gives the lowdown on the war of words between the Khans.

"At the party, Sallu started making digs at Shah Rukh without provocation. Initially he ignored the sarcastic comments as he realised that Sallu was delkiberately trying to draw him into a fight.

He politely excused himself but Sallu followed him and passing nasty remarks on Aishwarya (and not the other way round, as reported) He hinted that SRK had some association with her. SRK lost his cool and shouted back.

Aamir, who was also at the party intervened but got shoved by Salman."

The source adds, "For the last couple of days, Salman has been sending out feelers to patch up but SRK is in no mood to forgive!"
