Comic-Con, the four-day event to promote comic books and science fiction movies, TV shows, and more happening in San Diego right now, got a major fashion upgrade when a slew of sexy stars hit the red carpet Friday to publicize their upcoming projects.

Jessica Biel, 29, attended the Total Recall discussion panel in a Christian Cota silk trapeze-style cropped top with pale pink shorts that showed off her toned legs.

Anna Paquin, 29, tried out the red-hot dress trend at HBO's True Blood panel in a cherry-hued Antonio Berardi mini and black Gucci open-toe heels.(See more pictures of Paquin from PopSugar!)
