The new couple was snapped holding hands and packing on the PDA while grabbing breakfast on the go and strolling in a local park in the romantic Mexican resort town. The pair kept it casual with Luna sporting a blue button-down and khaki shorts, while Waterhouse donned a sheer lavender top and black, lace-trim shorts.
The 25-year-old model has been keeping things low-key with her new beau, sharing several selfies from the trip where Luna is nowhere to be found. Perhaps he's the one behind the camera? So sneaky, Suki!
The 37-year-old Mexican actor also stealthily shared a beachside snap of the romantic vacation, writing, "Waking up in paradise!! #tulummexico"
While Luna was previously married to actress Camila Sodi, with whom he shares two children, Waterhouse separated from Bradley Cooper in 2015 after dating for two years.
