Mumbai, Aug 4 (IANS): Bollywood heartthrob Salman Khan is known to be straightforward but the actor, who will be the new host of reality show "Bigg Boss 4", says he knows his limits and will not be disrespectful to anyone.

"I'm straightforward, but I'm not an obnoxious kind of guy who doesn't know what to say and where to say. I know that if I'm speaking to an elderly person, I should give him respect and if I'm speaking to a person junior to me, I should give him respect too," Salman told IANS in an interview.

"I know my limits. There is no reason to be disrespectful to anyone."

"Bigg Boss" is the Indian version of popular British reality show "Big Brother". It has celebrity contestants locked in a house under the surveillance of multiple cameras for a period of three months without any contact with the outside world.

Salman has stepped into the shoes of the host for the fourth season. The show has been earlier hosted by actors - Arshad Warsi, Shilpa Shetty and Amitabh Bachchan.

This year Shah Rukh Khan and Akshay Kumar's names were doing the rounds as the new host, but finally Salman's name surfaced.

So what newness does the 44-year-old actor plan to bring to the show?

"I haven't planned anything, whatever I do will be spontaneous. So I really don't know what is that new (thing) that I'll bring to the show. I'll be what I am," he said. "I'll just try to make it fun," he added.

Salman, who earlier hosted the game show "Dus Ka Dum", is known to connect with the audience very well.

Asked about one quality that helps him click, the actor said: "I don't know. I have no idea. The day I get to know, I'll be the biggest fraud on earth because when you come to know that, then you keep doing more of that to attract the audience. You are not natural then," he said.

Asked which medium he finds finds more challenging, films or television, Salman said: "In films there are a lot of re-takes, you are playing a character. But in television, you are what you are. Also, it's difficult to retain the attention of the public for a long period of time. So television is definitely tougher."

The show is expected to go on air from October this year with 14 new celebrities locked in a house for close to 85 days - with 35 cameras following their every move.
