Despite not starring in the film, Miley Cyrus definitely took the spotlight at the Los Angeles premiere of Isn't It Romantic. The star showed up in place of husband Liam Hemsworth (who was dealing with health issues) in a fiery, sheer Valentino gown from the pre-fall 2019 collection. With plenty of ruffles, volume and a matching lip, it was the perfect red carpet look.
