The news doing the rounds is that busy actress Kareena Kapoor would not be able to join her loving sister Karisma Kapoor's birthday on June 25.

Ironically it is Bebo's beau who seems more concerned about missing Lolo's birthday bash.

A source said, "Saif gets along like a house on fire with Karisma and her husband Sanjay. The two guys often share a lot of outdoor fun activities together. Saif doesn't want that he and Kareena should miss her sister's birthday this year."

Chotte Nawab's worry and guilt for the sisters not being together on the special day get heightened by the truth that Bebo would be shooting for his upcoming flick Agent Vinod in Morocco on Karisma's birthday.

Kareena rules out that possibility of Karisma flying down to Morocco, "How can my sister fly down to Morocco? No, she'll be in Mumbai with her baby. She has just had a baby boy who's not even four months old. She can't leave the city."

Interestingly Kareena seems to handle her absence from this important day in her sister with much pragmatism and common sense.

The busy sister said that she would not even have time to purchase a gift for Didi this year.

"There's no time to breathe. Forget buying anything. I don't know whether I'm coming or going," Kareena said.

The actress has never missed any of her sister's (Karisma) birth anniversaries. In recent years, Kareena had quite often gone to join Karisma in Delhi when the elder sister was staying in the Capital with her husband.

This time Kareena is trying to concentrate on Saif's home production rather than on Karisma's birthday. (With Inputs from Agencies)
