Looks like all that jogging with Scarlett Johansson is paying off! Sean Penn showed off his surprisingly well-toned beach body when he embarked on a jet-ski adventure with a lady friend in Malibu over the weekend.

The Oscar-winning star strutted around the beach in blue and black board shorts before mounting a jet-ski with rumored new girlfriend Stacey Koplin in tow. After splitting from wife Robin Wright, Sean has been spotted hanging out with a number of gorgeous young women, including Iron Man 2 beauty ScarJo.

Despite having a much-publicized smoking habit, Sean has adopted a new, healthier lifestyle after splitting with his actress wife. The star and activist has been spotted jogging with friends (including Scarlett) and exercising. Looks like that new healthier lifestyle is really turning back the hands of time!
