The brunette star, 21, donned a stunning black, purple and silver Vera Wang dress with a lace panel on the bust before hitting the showbiz event in Los Angeles.
Selena swept her glossy locks into a loose ponytail and accessorised with a dazzling pair of purple jewel earrings and Jimmy Choo black lace heels.
She completed her look with smokey eyeshadow and thick black eyeliner, which complimented her dark brown peepers perfectly, and a slick of pink lipstick.
Selena stars alongside actor Ethan Hawke in thriller movie Getaway, which is released in the UK next month.
