Drew Barrymore and Will Kopelman celebrated their daughter Olive's first birthday weekend with a day at Central Park in NYC on Saturday. The adorable family of three met up with friends during the daytime outing and took turns playing on the swings and in the grass with Olive, who turned 1 on Sept. 26. Drew and Will both made sure to shower their little one with lots of kisses as they rang in her milestone. The Barrymore-Kopelman clan has been spending most of the month in Manhattan and filling their stay with lots of work and play. In between showing Olive around the Big Apple, Drew recently stepped out for the New York City Ballet's Fall Gala and also spent an afternoon with Lucky magazine editor in chief Eva Chen, which could mean another upcoming spread in the publication for Drew since her last cover spot back in April.
