The 31-year-old hunk - who has been married to Jenna Dewan for nearly three years after they met on the set of `Step Up` - likes to constantly surprise the brunette beauty by writing messages and placing them around the house for her to find.
He told People magazine: "I see caring for somebody as a creative outlet. I like drawing little faces and writing little stories and hiding them in places.
"I`m a practical joker. My favourite one is putting one under the toiletseat. She always wakes up before I do, so I enjoy the surprise of, `Haha! I got you!` "
But Channing - whose latest acting role in `The Vow` sees him play a husband who has to try to make his wife fall in love with him all over again after she loses her memory in a car accident - finds it simple enough to be a "thoughtful" lover because he cares about Jenna so much.
He added: "I don`t think it`s that hard to be thoughtful, especially when you do care about the person."
