And you don't have to look very far to understand the source of his contentment.
Lingerie model Emma Heming, whom he wed last year in an idyllic beach wedding on the Turks and Caicos Islands, is a constant presence at his side.
"I am the happiest I've ever been and this comes after a long period of being kind of lonely," he told the Sun.
So happy in fact that he's cutting back on work because "I never want to spend one moment away from her".
While being full of praise for his 32-year-old wife's "spirit and class and beauty", what the screen hardman most appreciates is that she isn't with him for his fame.
"With Emma I knew I had found a woman who didn't need or want anything from me other than for us to be together and be happy".
His current wedded bliss is in stark contrast to the years following his divorce from Demi Moore when he turned to friends for advice.
"It was a tough time for me during those years after the break-up, but I had a long talk with Will Smith one day".
Their chat led him to try and remain on good terms with ex-wife Demi, the mother of his three daughters.
"He kind of explained to me how I had to make an effort to be good friends with Demi for the sake of our girls and how they would have a happier life and feel so much better if Mum and Dad could stay friends".
