enjoyed some time away from Gossip Girl
and the Upper East Side
for a burger date with beau Leonardo DiCaprio
in L.A. The couple
tried to stay under the radar at Umami Burger in Los Feliz, Calif., as they quietly ate. "Blake looked very happy and kept smiling," an onlooker tells us. DiCaprio appeared to enjoy himself, too. Says the onlooker: "He gently grabbed her hand at one point and he seemed very into Blake."
