It's official – Drew Barrymore
is a bride-to-be.
With news that she's set to wed Will Kopelman
breaking earlier Thursday, the star's rep confirms the engagement to PEOPLE and shares a sun-soaked photo of the pair.
At center stage? Barrymore's wide smile and that sparkler – a radiant-cut diamond
, just under 4 carats, set on a diamond-covered band – designed by Graff and given to her over the holidays by her art consultant beau in Sun Valley, Idaho.
Barrymore, 36, has been linked to Kopelman since February 2011
