Drew Barrymore was joined by her famous pals Cameron Diaz and Scarlett Johansson as she tied the knot with Will Kopelman.
The pregnant actress and her groom enjoyed a private ceremony in the garden of her Montecito estate in California, where they were also joined by her film director godfather Steven Spielberg and actress Reese Witherspoon, according to reports from the US.
E! Online said 37-year-old Drew wore a white pleated Chanel gown created for her by Karl Lagerfeld.
Guests were invited to a pre-ceremony cocktail party on the lawn before the traditional Jewish ceremony, and The Wedding Singer star Drew booked an 80s tribute band for the reception that followed.
A source told People magazine that it was a "classic, simple, very pretty garden-inspired wedding".
The happy couple were later snapped sharing a kiss as they were driven off in a classic Mercedes to the nearby San Ysidro Ranch for their wedding night.
