Wow, Josh Hartnett apparently caught the kissing disease from Scarlett Johansson. They dated for a year. While filming 30 Days of Night, he apparently was very sick. Eventually, they realized that he had glandular fever.

Glandular fever is usually seen in teenagers. The symptoms are usually fever, sore throat, muscle weakness, and fatigue. Symptoms usually appear 1 -2 months after exposure.

Josh Hartnett is definitely hot! I bet there are a few ladies out there that would risk it to get the chance to smooch those lips.
