Two telly-family queens will unite during this week's "Koffee With Karan", as they animatedly chat with the filmmaker about rivalry, weight gain, Amitabh Bachchan, Salman Khan and anything under the sun.

Smriti 'Tulsi' Irani and Sakshi 'Parvati' Tanwar are all set to wash away rumours of their rivalry Friday as they let their hair down to be seen in their true selves - giggling, bantering and bitching about the things that matter most to them.

"I think Tulsi and Parvati are twins separated at birth," says Smriti, the protagonist of "Kyunkii Saas Bhi Kabhi Bahu Thi".

"A lot of journalists say there's some rivalry happening. But what mostly transpires between me and Sakshi is we sit together and crib about everything."

She also reveals why she looks overweight. "I did try to lose weight and I started looking younger than my screen-son Gautam who is actually my classmate from school."

For Smriti, the sexiest man in India is her husband, Mallika Sherawat is a "phool jhadi" and Amitabh Bachchan is the right actor in the Parliament.

Not one to be left behind, Sakshi of "Kahani Ghar Ghar Ki" thinks Abhishek Bachchan is the hottest hunk in Indian cinema and Salman Khan is "mind blowing".

Her dream role was Rani Mukherjee's in "Black". Asked why she thinks her show "Kahani..." is better than Smriti's "Kyunkii...", pat come the reply: "Because the characters are more human".

Watching the two ever-suffering TV matriarchs fighting over Karan Johar's gift hamper is quite an experience.

Says Johar: "I haven't brought any TV stars on my show so far. Bringing the two most popular characters from the soaps together was my channel's (Star) idea. I was game. And I'm glad. Smriti and Sakshi turned out to be great fun, witty intelligent and utterly unaffected."
