Drew Barrymore was a vision in white Thursday.

The pregnant bride-to-be, 37, paired a floor-length Chanel gown with a black blazer at the New York City Ballet's 2012 Spring Gala at the David H. Koch Theater in Lincoln Center Thursday. She was joined by her fiance, Will Kopelman, 34, who lovingly escorted her down the red carpet.

"Drew looked great and was smiling the entire time," an observer tells Us Weekly. "Drew whispered something in Will's ear and kissed his cheek as they walked inside. They had their arms hooked together as well."

The Big Miracle actress and her art consultant beau will tie the knot this June because Barrymore "wants to get married before the baby comes, but doesn't want to be huge," a pal recently told Us.

Barrymore will reportedly wear Chanel for her ceremony, which will be held at her Montecito, California home. "She is really focused on the wedding right now," a friend told Us. "She will be even more excited about the baby after that!"
