Filmmaker Karan Johar's talk show "Koffee with Karan" is becoming more intriguing. Each episode and guest list gets hotter by the week. He has now roped in Shilpa Shetty and her sister Shamita to appear on the show.

"How can I refuse Karan? No one says no to him. I'll be coming back from London in April to record my 'Koffee' with Karan. Shamita will be on the show with me," Shilpa told IANS.

Karan also wanted her mother Sunanda to join them on the show. "But you know how my mom is? She has declined."

Shilpa will be discussing her entire "Celebrity" Big Brother" experience for the first time on Indian television, and also the impact the British reality TV show and the racism row it triggered off had on her family.

Definitely a coup for Karan! But hold on! He plans to bring on an even bigger blend of celebrities in a future episode.

Karan actually intends to bring together Amitabh and Abhishek Bachchan with to-be daughter-in-law Aishwarya Rai, plus maybe Jaya too.

Ambitious?

"Well the guest list has to get bigger and more ambitious, don't you think? Otherwise, what's the point of having the show," reasoned Karan.
