Arianna Huffington hosted a special luncheon for Jennifer Aniston to celebrate the upcoming release of her film Cake at her Los Angeles home.

Jennifer Aniston’s ‘Cake’ Party

Huffington threw the lunch party on Tuesday in honor of Aniston, who has received rave reviews for her turn as a depressed and drug-addicted woman suffering from chronic pain in Cake. Aniston brought her fiancé, Leftovers star Justin Theroux, with her to the event and raised a glass of champagne to her close friend Chelsea Handler as Huffington delivered a toast.

Huffington took to Twitter during the celebrations to post a picture of herself with the former Friends star, writing, “At my home in LA celebrating Jennifer Aniston & Cake, an amazing film putting spotlight on mental health & addiction.”

Aniston’s Friends costar and real-life pal Lisa Kudrow was in attendance at Huffington’s party, as were actresses Nia Vardalos and Salma Hayek.

In Cake, Aniston’s character Claire struggles with day-to-day life after a car accident leaves her in chronic pain, her son dead and her marriage broken. Embittered by the loss of her child and wracked with severe physical agony, she becomes addicted to her pain pills and starts to see visions of a woman in her support group who committed suicide (Anna Kendrick), and finds an unconventional friendship with the dead woman’s husband, played by Sam Worthington.

Aniston has received Golden Globe, Screen Actors Guild and Critics’ Choice nominations in the best actress categories. It’s thought likely that Aniston will also receive an Oscar nomination for her performance.

Cake hits theaters in wide release Jan 23, 2015.
