The couple wasn't afraid to get cozy, sharing a steamy kiss in the water.
Lourd, 24, wore an itsy bitsy bikini for the day, showing off plenty of skin.
Meanwhile, Lautner rocked blue swim trunks.
The actress had a major victory in her career recently, bagging a slot on the upcoming season of American Horror Story.
But it's still been a tough time for Lourd.
Lourd, 24, captioned a photo of Reynolds wearing a green sweater and pants with mom Fisher standing behind her, “Happy 85th to my constantly classily clad Abadaba.”
