Karisma Kapoor who turns 38 this month will celebrate her birthday with her sister Kareena's future family. Kareena Kapoor was with Saif Ali Khan's family at a dinner party hosted in the memory of Saif’s father the late cricketer Mohammed Ali Khan. Kareena who shares a special bond with her sister Lolo, has planned for a simple birthday party in London. Karisma is expected to join the family this weekend.

However, insiders say that her current relationship trouble with her husband Sanjay Kapur, who was rumoured to be secretly dating Priya Sachdev and had also asked for a legal separation, is the reason for her London trip. They further added that Kareena did not want to leave her sister alone during this phase.
