Kopelman proposed with a colorless, radiant-cut diamond ring by Graff, according to People. A source told the magazine that the pair "are very happy together."
Barrymore and Kopelman, the son of former Chanel CEO Arie Kopelman, went public as a couple in last February, according to Us Weekly. A source said they dated briefly in 2010 but split at the time, and reunited the following year.
This will be the actress' third marriage. She was married briefly to bar owner Jeremy Thomas in 1994, and wed comedian Tom Green in July 2001 (he filed for divorce that December).
