Ari Perilstein/Getty Images for LTLAJennifer Aniston looked radiant in a bright coral Calvin Klein Resort 2015 nylon mini dress at a screening for the film Cake and cocktail after party on Friday night in Los Angeles and cozied up on-camera to fiancé Justin Theroux.
The 45-year-old actress's outfit was designed by Francisco Costa, the brands' Women's Creative Director. Aniston paired the look with silver stiletto pumps, shoes she appeared to have also sported at a recent premiere for Horrible Bosses 2, another one of her new movies that hits theaters on Nov. 26.
Aniston and Theroux have been engaged since April 2012 and have not announced a wedding date to the press. The actress sported her stunning 8-carat engagement ring at both events.
She and Theroux also attended a Horrible Bosses 2 after party at Sadie Kitchen & Lounge in Los Angeles. They were joined by her fellow former Friends co-star and bestie Courteney Cox and her fiance, Johnny McDaid, as well as her movie co-stars Jason Bateman and Jason Sudeikis and Chris Pine. The group enjoyed late night eats and cocktails, while a DJ spun music throughout the night, a source told E! News.
In addition to Friends and the Horrible Bosses film, Aniston is known best for her roles in other comedy movies, such as We're the Millers and Office Space. Cake marks one of her most somber performances.
"It was the hardest job I'd ever, you know, taken on and I loved every second of it," she told E! News. "It was hard. It was five weeks in and out and I was saying, you know it's a hard body to live in, but told a good story."
The actress, known for her slim figure, underwent a body transformation for the drama film (see pics) and also wore no makeup while filming it.
Aniston said she "just didn't work out for two-and-a-half months" to prepare for her role as woman who attends a chronic pain support group and is dealing with a personal tragedy. She and a widower who is also a member develop a relationship after she becomes fascinated with his wife's suicide.
The movie also stars Sam Worthington, Anna Kendrick, Chris Messina and married couple Felicity Huffman and William H. Macy.
Cake is set to have a limited release in December, making it eligible for an Oscar nomination, and hit more theaters in 2015. The nominees are set to be announced on Jan. 15 and the ceremony takes place on Feb. 22.
