The Cannes Film Festival officially kicked off on Tuesday, and all eyes were likely on Selena Gomez as she made her first-ever appearance. Clad in a sexy all-white ensemble, the 26-year-old singer was on hand to promote her new star-studded film, The Dead Don't Die. Selena was joined by her costars, including Adam Driver, Bill Murray, Tilda Swinton, and Chloë Sevigny. Prior to her debut, Selena posted a series of selfies on Instagram, writing, "hi Cannes…you're very pretty." The horror-comedy was directed by Jim Jarmusch and hits theaters on June 14. It centers around a town called Centerville that suddenly finds itself overrun with zombies. Given that the festival is 11 days long, hopefully this means we'll be seeing more of Selena in the days to come.
