The Secret Life of Walter Mitty star gave single mom Theron, 38, a helping hand by carrying Jackson for her on the sand. Penn cuddled the little boy in his arms and gave him a sweet kiss on the head. The happy trio dressed in warm sweaters and boots for the sunset stroll.

During the stroll, Theron also showed some PDA towards Penn by wrapping her arms around him as they watched Jackson run on the beach with two dogs.

The South African star was first rumored to be dating Penn when they were photographed ringing in the New Year together in Hawaii. Piers Morgan confirmed the Oscar winners were a couple in a Jan. 18 blog post recalling a conversation he had with Penn at the Jan. 11 Help Haiti Home gala.

"At 2 a.m., Sean came over, and bear-hugged me," the Piers Morgan Live host wrote. "'Congrats on a great night,' I said. 'And congrats on Charlize too.' He laughed. 'She's a keeper, that's for sure . . . well, I'll do my best to keep her anyway!'" 

Since then, Penn and Theron have been photographed on several outings together including a PDA-filled trip to the grocery store on Jan. 22, and a romantic getaway to San Francisco on Jan. 26.
