Looking good, Drew!

Less than one month after welcoming daughter Olive, Drew Barrymore showed off her post-baby body during an Oct. 18 outing with husband Will Kopelman. Casually dressed in cuffed jeans, a graphic sweatshirt and red flats, the actress, 37, strolled alongside her man as they grabbed lunch at Three Pickles in Santa Barbara, Calif.

Though Olive was born on Sept. 26, her proud parents waited until Oct. 1 to announce that they had expanded their family. "We are proud to announce the birth of our daughter, Olive Barrymore Kopelman, born Sept. 26, healthy, happy and welcomed by the whole family," the couple told Us Weekly in a statement at the time. "Thank you for respecting our privacy during this most special time in our lives."
