Jennifer Lawrence is a massive star, so Dior will be paying dearly for these commercials, and she will be worth it!

Bradley Cooper’s new film, “Silver Linings Playbook,” is getting some great reviews, and a bunch of stars joined Cooper at the Weinstein Company’s “Silver Linings Playbook” special event with Lexus and Purity Vodka at the Chateau Marmont in LA. Co-star Robert De Niro was among the guests as you can see in the slideshow above, along with Zoe Saldana, Naomi Watts, Diane Keaton, Jane Fonda, Mel Gibson, Christian Slater, Thomas Jane, Dermot Mulroney, Josh Brolin, Eric Dane and Rebecca Gayheart. The drinks were flowing as the guests enjoyed various martinis made with Purity Vodka. Zoe Saldana and Naomi Watts looked great as you can see above.

Check out the trailer. Unfortunately we didn’t see any pics of co-star Jennifer Lawrence at the event, but the others seemed to have a great time.

Even Mel Gibson made a rare appearance.
