Showstoppers! Julia Roberts and George Clooney brought their fashion A-game as they attended the premiere of their new film Ticket To Paradise on Monday
This marks the fourth time the Hollywood stars, who play exes on a mission to stop their daughter from making the same mistake they did 25 years ago by marrying young, will reunite for a film.
In the film their characters’ daughter Lily (played by Kaitlyn Dever) meets the love of her life on a post-graduation jaunt to Bali, which is where her parents must travel to in order to change her mind.
However, judging by the trailer it looks as though Julia and George’s trip to save their daughter ends up being a journey in healing their own problems with each other.
From fighting over being sat next to each other on the same plane, to ending up doing tequila shots and embarrassing their child by dancing – it seems as though there could be a reconciliation on the cards.
