Having lost weight before leaving for the Rock Stars concerts, Kareena Kapoor is making waves in the United States and says both she and Shahid Kapur are overwhelmed with the response.

"The concerts are going unbelievably well. We have finished our performance in Washington. And the ovation is unreal. For Shahid it is the first time. He has never done live concerts before. And he is having a ball like me," Kareena told.

Kareena says the Rock Stars concerts are the best live shows of her career. "Every performance of mine from 'Yuva' to 'Chameli' to 'Fida' has the audiences on its feet."

Going into the details of the concerts, she says, "Shahid and I have an act together. I also have a dance number with Salman Khan. We have just finished Washington. Our next performance is in Boston. After that we will perform in Chicago, New York and then Toronto."

"Everywhere we go the screams of the audiences follow us. I tell you it is unreal. To watch them go insane after our performances gives me a high that I can't put into words."

Despite having an abbreviated role in her latest release "36 China Town", Kareena says the film has done quite well.

"Shahid and I have been accepted as a pair. We will now be seen in Priyan's (Priyadarshan) 'Chup Chup Ke'. I really don't think life can get any better... or may be it can."

Kareena returns on June 14 to join the unit of Farhan Akhtar's "Don" in Malaysia.

"It's just a special appearance in 'Don'. But my song 'Yeh mera dil pyar ka deewana' rocks. I know there will be comparison with the original (Helen in Chandra Barot's 'Don'). But all comparisons will be forgotten once people see what I have done."
