The 31-year-old model and the 51-year-old The Meg actor were spotted visiting a medical building on Monday (April 15) in Beverly Hills, Calif.
Jason kept busy on his phone as he walked behind Rosie, who was seen reaching into her tan-colored purse.
Rosie donned an all-black ensemble with green boots and earrings, styling her hair into a low bun. Jason also wore all black, along with a green baseball cap.
Just ahead of the weekend, the duo enjoyed a date night at Nobu in Malibu.
You can next catch Jason in Fast & Furious Presents: Hobbs & Shaw, out on August 2!
