Olivia Wilde and Jake Gyllenhaal seemed to be “very cozy” over dinner at Chinatown Brasserie. The stars, both single, were seated next to each other at a table of eight at the Lafayette Street eatery Saturday night. A spy said, “They were in a group but were very cozy with their chairs pulled in closely together.” They were also spotted one night in June at LA’s Chateau Marmont, but at the time her rep said they were “just friends.” Their reps didn’t get back to us last night.
