Gwyneth Paltrow, hot on the stylish heels of a bachelorette vacay in Cabo San Lucas, celebrated her engagement to Brad Falchuk with a triple-A-list party at the Los Angeles Theatre Saturday.
People magazine reports Gwyneth was a knockout in a maroon, one-shouldered gown with a slit up to there.
Fashionable friends who helped Paltrow party included Jennifer Aniston (sporting a wrist brace on her left hand), Cameron Diaz & Benji Madden, Julia Roberts & Danny Moder, Demi Moore, Kate Hudson & Danny Fujikawa, Steven Spielberg & Kate Capshaw, Karlie Kloss, Rashida Jones, Liv Tyler & Dave Gardner, Lake Bell & Scott Campbell, Jen Meyer, Sara Foster, Chelsea Handler, and Reese Witherspoon.
The black-tie affair was reportedly thrown by Ryan Murphy, Falchuk's co-creator of "Glee," "American Horror Story," and "Scream Queens."
Paltrow, 45, and Falchuk, 47, announced their engagement in January.
If reporting by DailyMail.com that the couple could have secretly married at the engagement bash fails to be confirmed, it's all right — it just means they'll get to enjoy another massive party and star-studded gathering in the near future!
