April 13 (UPI) -- Kourtney and Kim Kardashian dazzled on the red carpet Wednesday.
The reality star siblings mingled with singer Cher and actress Angela Sarafyan at the Los Angeles premiere of The Promise at the TCL Chinese Theatre.
Kourtney bared some cleavage in a black pantsuit with a plunging neckline, while Kim showed off her figure in a formfitting gold dress. Cher wore a biker-inspired outfit, while Sarafyan stunned in a lace gown.
The Promise follows a love triangle (Oscar Isaac, Charlotte Le Bon and Christian Bale) during the Armenian Genocide and final years of the Ottoman Empire. Kourtney, Kim and Cher are all of Armenian descent.
"So proud of the movie #ThePromise Everyone please go see it and finally hear the story of the Armenian people," Kim tweeted to her 50.9 million Twitter followers.
Kim has been making a gradual return to the spotlight since being robbed at gunpoint Oct. 2 in Paris. She said on the March 19 episode of Keeping Up with the Kardashians that she expected to be raped and killed during the incident.
"I would never wish this experience upon anyone, but have learned some valuable lessons & feel so blessed to be safe home w my babies & husband," the star tweeted after the episode.
"To my friends, family, and loved ones I can't thank you enough for being there when I needed you the most," she added. "I took a tragic horrific experience and did not let it diminish me, rather grew and evolved and allowed the experience to teach me."
