Even when he’s in the middle of hitting the waves, Hilary Duff’s adorable son Luca has time to show some love for his mom!

The singer posted a cute video of the 5-year-old boy enjoying some tubing fun on the water on Monday and after waving to the camera while proving his one-handed balancing skills, the youngster then threw in a quick kiss.

“Casual wave and an air kiss. ❤️?,” Duff captioned the video.

In another snap posted over the weekend, the headset-clad pair seemed to be having a blast while taking a flight.

Duff recently shared how Luca -- whose father is Duff’s ex-husband, hockey star Mike Comrie -- is starting to understand more about his mom’s work and fame.

However, magazine covers are no big deal to the cutie!
