The heroine of "Roswell" has become the new teen idol. American teens return to embark with her for Mars. At 22 years old, Katherine Heigl sees her career take off like a rocket, thanks to "Roswell". A rise which doesn’t make her giddy…

Télé Star: Since you became Isabel in "Roswell", do you believe in extra-terrestrials?

Katherine: I’m asked, it’s true, several questions about that. "And so finally there are things elsewhere?" Perhaps I would have some brief replies if I met the people who claim to have proof of extraterrestrial manifestations. But I have never had that chance.

Télé Star: Without having seen a UFO, the success of the series must have changed your life, no?

Katherine: I’ve been in this business since I was ten. Therefore, I was more prepared than the others for what would knock us in the heads one day or another. But yes, my life has changed a little: I find photographers hiding below my house, I have to control my attitudes, not be too demonstrative with my boyfriend… That said, I assure you, I don’t have too many worries. And then, like many have told me, if I don’t want to see my private life more or less in the public domain, all I have to do is change careers.

Télé Star: As a teen, were you as cool?

Katherine: (She bursts out laughing.) You want to laugh! I was the clumsy, uncomfortable in my skin. I used to have a very large waist and I was shaped like a lemon: no chest, no hips. From the beginning to the end of middle school, when I got to the locker room for gym, everyone made fun of me. For two years, I prayed every night for my breasts to appear. My physical transformation happened when I was seventeen, in 1995. When I finished filming "Under Siege 2", I had become more womanly, more sure of myself. I remember coming to high school and planting myself in front of the boys and saying, "Now it’s my turn to laugh!" My attitude had changed to the point where a lot of people thought I was strange.

Télé Star: How so?

Katherine: You know, in New Canaan, the little town in Connecticut where I was born, the people are pretty much conformists. And, of course, when they saw me wearing red worn out shoes and a jean jacket with the skyline of New York in rhinestones on the back, they thought I was crazy.

Télé Star: But who did that leave you to go out with?
