- Jenna: It was amazing. I started dance when I was five years old and danced pretty much throughout my life. Then at age sixteen, an agent – a dance agent from LA, actually – found me and asked if I went to LA if he could represent me. I said sure. So, right at eighteen I moved to LA and started auditioning. I went to college as well, I went to USC. I was auditioning dance-wise and just started booking work. Booked the Janet Jackson tour and was gone… And that was where my life took me in the beginning. (laughs)
- Jenna: (on the movie 'Tamara') My agent sent it to me for an audition. I read it and I loved the fact that to play Tamara you had to play two different characters. Not only two different characters, but completely different sides of the spectrum – the poor, picked on, unattractive girl and the vixen, the revenge-filled powerful woman. I knew it would be a challenge and I was really excited. And I always kind of wanted to do a horror movie, so I was excited about that. I really like the character of Tamara.
- Jenna: I'm about 50/50 when it comes to technology. I can check my email and search for stuff, but if I hear we're on this and this and this site, then I need an exact link to get there otherwise I'm going to get lost.
