The 18-year-old was catapulted into the spotlight with co-star Robert Pattinson when the epic Vampire love story stormed into international box offices last month (Nov08).

But Stewart admits their sudden success is overwhelming.

She says, "I'm really not good at it. Some people are great at it. It's like the other side of the job. I can't believe I have to do it.

"It makes it easier because I'm really proud of the movie and I'm a fan of the book as well.

"It's weird to see people mainly my age flipping out over Rob walking into the room. He shifts in his seat and they all just go crazy. It's a little daunting."
