He is in showbiz for more than two decades, yet Bollywood actor Aamir Khan was nervous before his ramp debut for Salman Khan's "Being Human" show at the ongoing HDIL India Couture Week. He said he wanted to go back home.

"I was extremely nervous because I have never done it before. I am not used to doing all this. This is not my world. But I did it just for my friend Salman and to support the cause," Aamir told reporters Tuesday after the show.

"When I was rehearsing, the show area was empty still I was nervous. I thought that when I'm nervous now, what will happen when I will walk the ramp in front of the audiences. And I thought I should go back home," he added.

Before starting the walk, the actor stood on the ramp for a second, looked around, smiled at everyone, took a deep breath and very shyly started walking maintaining eye-contact with the audience and acknowledging their cheers.

Despite his nervousness, he charmed everyone with his boyish looks and cute smile.

Once he got over the initial inhibitions, Aamir entertained people by dancing with the kids who had initially done a small jig at the beginning of the show.

Ajay Devgn, Akshay Kumar, Saif Ali Khan, Govinda, Sanjay Dutt, Katrina Kaif, Arbaaz Khan, Salman Khan and Sohail Khan too walked the ramp.

Other than Aamir, Ajay Devgn too made his ramp debut and he was also very scared before walking down the ramp.

Actress Amisha Patel, who was there to support the cause, told IANS that the nervousness of these actors was very evident, as they had never walked the ramp before. But it was good to see them all come together for a good cause.

Another shy actor and Salman's good friend Sunny Deol too was supposed to make his ramp debut.

"He was here but he is very shy. He didn't know that he had to walk the ramp. As soon as I told him, he hid somewhere," said Salman jokingly.

"He was telling me behind the ramp that he would be there," he added.
