The 38-year-old actor and 20-year-old Victoria's Secret beauty recently visited the Palace of Versailles for some sightseeing together.
DiCaprio sported a casual red tee, pants and cap for the cultural outing. Garrn looked pretty in white top, short shorts and black sunglasses. The couple walked around the palace and took pics of each other.
Earlier today, Garrn posted a photo of herself and a female friend watching a French Open tennis match between Novak Djokovic and Rafael Nadal.
"Perfect day off with @cdicalypso watching Novak vs. Rafa #rolandgarros..unfortunetly we can't cheer together," the German-born beauty posted.
Garrn was first spotted with DiCaprio at the end of May while hanging friends at a Grand Prix party in Monaco.
