They got engaged in Sun Valley, Idaho, a source tells PEOPLE. And her ring is by Graff, and
”They are very happy together,” adds the source.
It had been over the Christmas holiday when Barrymore had spent ten days in Sun Valley with Kopelman. When they had been seen at the romantic Vintage restaurant and picking up organic salads at Kiki’s Café.
Onlookers had explained to PEOPLE when spotted out and about, the couple graciously posed for pictures. The two have never officially admitted to their relationship, but they have been linked together since February.
