The 20-year-old actress/singer went glam in a diamond-covered corset and frilly pink skirt for the premiere while her 24-year-old co-star paired a black suit with bright white sneakers.
Based on the Japanese film, Midnight Sun centers on Katie (Thorne), a 17-year-old sheltered since childhood and confined to her house during the day by a rare disease that makes even the smallest amount of sunlight deadly. Fate intervenes when she meets Charlie (Schwarzenegger) and they embark on a summer romance.
Midnight Sun hits theaters on March 23!
FYI: Bella is wearing a Raisa & Vanessa dress with Norman Silverman diamonds.
