Gwyneth Paltrow‘s engagement party may have been a black tie event, but there was nothing stuffy about the romantic celebration.
“It was an old-school and very glamorous Hollywood event,” a source tells PEOPLE of Paltrow and fiancé Brad Falchuk’s celebration, adding that “even with all the celebs, it wasn’t a stuffy party.”
“Instead, lots of candles and fragrant flowers created a romantic atmosphere. It felt intimate and very special. You could tell that all guests very much love the couple,” the source continues.
Guests at Paltrow and Falchuk’s Los Angeles bash included Jennifer Aniston, Cameron Diaz and her husband Benji Madden, Julia Roberts, Demi Moore, Reese Witherspoon and Kate Hudson, who’s currently expecting a daughter with boyfriend Danny Fujikawa.
