They haven’t walked down the aisle yet, but Drew Barrymore and her fiancé, Will Kopelman, looked like they were already on an extended honeymoon at the afterparty for her new movie Big Miracle Wednesday night in Washington, D.C.
“They were very affectionate the whole night, holding hands and turning into each other to have their own intimate conversations,” says an eyewitness. “He never left her side. They were a team from the beginning to the end.”
While Barrymore mingled with partygoers – many of whom were family members of fallen soldiers – Drew would always “introduce and encourage her fiancé to be part of the action,” says one onlooker. (Her other mission? Kindly asking the children at the party not to reveal the film’s ending.)
