They are the most sought after onscreen and offscreen couple and individual stars, but Abhishek and Aishwarya Rai Bachchan say they would never rate each other professionally.

Having worked in six films together, the couple is going to rub shoulders again for Mani Ratnam's upcoming movie "Raavan" and analysing each other at work is the last thing on their mind.

"We don't rate each other. We just like working with each other as co-actors, " Aishwarya, 36, said via telepresence from Mumbai late Friday night.

"Abhishek is a very free actor. He breaks himself free. He works as a team member and doesn't act as a male lead or anything of that sort (on work), " added the former Miss World-turned-actress, who was wearing a white salwar kameez and a pink dupatta.

"He is a team mate fulfilling his director's vision in every which manner he can and a pleasure to work with, " she added.

Her actor-husband chipped in: "We don't criticise our performances. As a wife, Aishwarya has always been equally and completely supportive and more than that as a co-actor, she does everything to make it go right. She does not ever compromise even on her co-star's work."

" (And) as a couple we never bring work home...that's a rule, " added the actor, who was sporting a pink shirt and a black suit.

The pair earlier worked together in films like "Dhai Akshar Prem Ke", "Kuch Naa Kaho", "Umrao Jaan", "Dhoom 2", "Guru" and "Sarkar Raj".

The couple, who married in 2007, was speaking through video conferencing that ran simultaneously for more than two hours across the capital, Mumbai, Chennai, New York and Dubai to promote "Raavan".

Also present with them were Ratnam and Tamil superstar Vikram from the southern city. Vikram makes his Bollywood debut with the movie.

Releasing June 18, "Raavan" is a bilingual, co-produced by Reliance Big Pictures and Madras Talkies.

In the movie, Abhishek plays outlawed local hero Beera Munda, who kidnaps Aishwarya (Ragini), wife of Vikram (police officer Dev). As the story progresses she reportedly develops a soft corner for her abductor.
