All eyes were on Jake Gyllenhaal as he walked into Osteria Mozza in L.A. with a guy friend after 11 p.m. The actor was greeted with a hug from Adam Levine (of Maroon 5), and the trio spent the night chatting and sipping cocktails. The next morning, a casually dressed Gyllenhaal stopped for breakfast at Blu Jam Café with another group of friends. “They were laughing and looked like they were having a great time,” says an onlooker of Gyllenhaal and his posse.
