The notoriously private couple, who reportedly got engaged earlier this year, dazzled on the red carpet at the premiere of the actor's latest flick. Rooney joined her leading man and his incredibly large family at the star-studded event, grabbing a whole lot of attention in a skin-baring two-piece ensemble.
The coolest thing about her red carpet look is that she designed it herself! The look is part of her animal-product-free collection Hiraeth.
The couple, who met in 2016 on the set of the film "Mary Magdalene," first made their debut at the 2017 Cannes Film Festival closing ceremony. Since the, they've mostly managed to keep their romance on the down low. Earlier this year, however, Rooney was spotted with a diamond ring on that finger. Us Weekly then confirmed her engagement to Joaquin.
