It is one of the most successful and loved Director-Actor jodi. When Karan wrote his first film and was set to direct it, Kajol was an obvious choice. While he was making his debut with ‘Kuch Kuch Hota hai’, she was already a superstar. They had already worked together in “DDLJ”. With this film their friendship turned into a commercial success story also. They went on to have another hit in ‘K3G’. As Kajol took a break from movies after marriage, she continued to make cameo appearances in KJo’s films. It was Karan who made her return to Bollywood for ‘My name is Khan.’
