/> It's final and irreversible. The long-delayed Saif Ali Khan production Agent Vinod is finally releasing on March 23.

Confirming this as the final release date director Sriram Raghavan reveals that the celebrity couple shot for the last day of Agent Vinod on December 24.

Says the softspoken director, "My shooting with Saif and Kareena is over. We are all done. Saif and Kareena did their last shooting for my film on December 24 and left for their holiday. We are now in post-production work. The release date is March 23. "

The Kareena-Saif wedding would follow in the last week of March or the first week of April.

This confirms our earlier report that the next schedule of Madhur Bhandarkar's Heroine has been preponed from the end of February to the middle of February to accommodate the promotion and release of Agent Vinod into Kareena's clogged schedule, followed by the wedding and honeymoon.

Says a source, "After the release of Agent Vinod the wedding will happen immediately. Kareena and Saif don't want to delay it any more. "
