She has been making a growing number of television appearances to promote the last instalment of Twilight, but has as yet not addressed her fling with married director Rupert Sanders, which made headlines the world over. And Kristen Stewart still keeps it strictly business, on a forthcoming appearance on The Tonight Show with Jay Leno, judging by a new preview clip.?

The 22-year-old actress discusses the ending of Twilight and doing stunts as alter ego Bella Swan during the sit down chat on Monday.

The star talked about Bella's new energy as a vampire after she was turned at the end of the last film and having to do stunts like wrestling a mountain lion and jumping into waterfalls.

'It was scary,' she admits. 'I made really embarrassing sounds the first time I did it. But then you get used to it. I can be badass after that.'

The star looks stunning in a stunning patterned colourful dress with her hair pulled into a simple ponytail.

Earlier, she had looked a little more low key as she arrived at the Hollywood studios in a white T-shirt and baseball cap to discuss Breaking Dawn Part II, which will be released in the U.S. on November 16.

'It is so shocking to be honest,' the star says about the ending 'with a twist.' She added: 'I can't even think about it, I get giddy.'
