The 26-year-old beauty is sick of being viewed as a sex symbol and wants to land some serious acting roles.
Jessica told America's GQ magazine: "I hope all my new work will help producers in getting past my hotness.' The 'Sin City' star has five films coming out this summer, including comic book blockbuster 'Fantastic Four: Rise of the Silver Surfer', comedy 'Good Luck Chuck' and thriller 'Awake'.
Jessica - who recently topped FHM magazine's annual 100 Sexiest Women in the World poll - also insists she is very shy, despite her overtly sexual image.
She said: 'I try not to make the headlines. I'm self-conscious about this. I try to not make my presence known.
'I have my own fashion style and do not try to fit in. I don't have my breasts under my chin, I'm not showing butt cheeks, nor much legs. I don't go for the trendiest look.' Jessica recently claimed she wants to be a 'serious actress', and does not want her movies to be all about 'me in a bikini'.
The screen beauty was seen in swimwear for almost the entire duration of ocean adventure movie 'Into the Blue'.
