Tomorrow marks the official start of the 2010 Comic-Con, but the stars are already gearing up for the anticipated event. "Supernatural" star Jim Beaver told followers, "Finished my Supernatural scenes--headed home tomorrow, on to Comic-Con this weekend," while dearly departed "Vampire Diaries" actress Malese Jow tweeted, "I'll be at Comic Con (7/24) from 12-2pm at the Arcana booth #2415 signing for the release of Koni Konfidential!... http://fb.me/DFVnWHvX."
The sequel to "Mean Girls" also has fan girls a-buzzing this week. Production is already underway and the flick's stars are keeping us in the loop (so fetch!) Meaghan Martin (pictured) posted, "It is so hot. Exterior scenes for Mean Girls 2 are killer" and her co-star Diego Boneta was feeling the heat, too, writing, "Just arrived to the hotel after shooting with a bunch of Mean Girls :)It was really hot out!!"
