Karan and Kareena painting the walls red

Monday was a special day for Karan Johar and Kareena Kapoor. The director and actress shot together for the first time after Kabhi Khushi Kabhie Gham.

Though it was for a paint ad, the point was well taken by the buddies who temporarily breached their bonding over Kareena's refusal to do Karan's Kal Ho Na Ho.

"That was in the past," Kareena brushes off the cold war. "I was headstrong immature and impulsive. I'd like to think I've matured in the past few years."

As the twosome exchanged buddy-buddy baatein on the set, it was easy to see that they were completely comfortable with one another, the past forgotten.

Karan was exhausted at the end of the day. "It isn't a tough commercial and Bebo today is easy to direct. She's focused and committed. We both had a ball today."

The commercial is part of a package deal for Karan with a major paint company. Shah Rukh Khan's company Red Chillies is producing the ad.
