Is Gwyneth Paltrow Wearing a Wedding Band?

Last night, actress and businesswoman Gwyneth Paltrow grabbed some attention after she was spotted with a ring on that finger!

At the pre-Broadway opening party for “Head Over Heels” at the Curran Theatre in San Francisco, Gwyneth went without her sparkling engagement ring, wearing another ring instead.

The ring in question had “BF” engraved on it, which could be a tribute to fiancé Brad Falchuk.

Over the weekend, Paltrow and Falchuk celebrated their engagement with a star-studded party whose guests included Jennifer Aniston, Julia Roberts, Cameron Diaz, Kate Hudson, and Demi Moore. The bash was thrown by Brad's "Glee" co-creator Ryan Murphy.

Gwyneth posted a pic on Instagram, captioning it, “Thank you @mrrpmurphy for the most incredible evening to celebrate our ❤️. There will never be adequate words to express our gratitude. @giambattistavalliparis I will never get over my gorgeous dress. @georgieeisdell thank you. @hairbylorenzomartin thank you. @teamsaltzman thank you. Thank you to all of our amazing true and dear friends who came to support us. We feel like the luckiest people on the planet because we have all of you in our lives. And most of all thank you @bradfalchuk for the true happiness.”

While some speculated that the event was a secret wedding, Page Six reports that it was just a super fancy engagement party.
