Drew Barrymore has a lot to celebrate – and she did so in style Friday night with a ritzy Manhattan engagement party.
The bride-(and mom!)-to-be and her fiancé Will Kopelman hosted 300 guests, according to the New York Post. That guest list included Barrymore’s Charlie’s Angels costar Cameron Diaz, and the group celebrated at the Press Lounge rooftop in the city’s Hell’s Kitchen neighborhood.
Guests sipped the hostess’s own Barrymore 2011 Pinot Grigio and snacked on wild salmon and spicy shrimp. Drag queen DJ Lady Bunny provided the ’80s music on an outdoor patio and the space was decorated with votive candles and a massive floral arrangement, according to the report.
