• Scarlett Johansson has just turned down the latest Marine seeking a celebrity date via YouTube — but will she kill the fad or stoke it? The actress told the blog zap2it that instead of attending the Marine Corps Ball with Georgia-based Sgt. Dustin Williams , she is sending him a case of champagne. Both Mila Kunis and Justin Timberlake have agreed to go to Marine galas this fall — she in North Carolina, he to Quantico — after grunts asked them for dates in clever YouTube videos.
