He recently revealed that he’s never truly felt loved, despite two past marriages.
But from the look of Sean Penn’s incredible physique on a beach in Maui Monday, the 52-year-old actor won’t stay single for long.
The two-time Oscar winner looked like he was in the best shape of his life as he strolled on the sand in nothing but blue snowflake-patterned swim trunks.
The Milk star – sporting shoulder-length hair and a mustache – used the picturesque Hawaiian getaway to flaunt his sinewy arms with bulging veins, six-pack abs, and defined pecs.
The outspoken political activist recently returned from Bolivia where he successfully convinced President Evo Morales to release a jailed American businessman named Jacob Ostreicher.
Penn focused on his humanitarian work when his 14-year marriage to actress Robin Wright ended in 2010.
‘There is no shame in saying that we all want to be loved by someone. As I look back over my life in romance, I don’t feel I’ve ever had that,’ the 21 Grams actor revealed to Esquire.
‘I have been the only one that was unaware of the fraud in a few of these circumstances blindly.’
The estranged couple co-parents two children – 21-year-old daughter Dylan and 19-year-old son Hopper.
Penn, who was also married to Madonna for four years, told the magazine that divorce made him realise the truth about his relationship with the 46-year-old Princess Bride actress.
‘When you get divorced, all the truths that come out, you sit there and you go, “What the f*** was I doing? What was I doing believing that this person was invested in this way?” Which is a fantastically strong humiliation in the best sense,’ he said.
‘It can make somebody very bitter and very hard and closed off, but I find it does the opposite to me.’
The single stud has romanced numerous beauties over the years, including models Brigitte Nielsen, Petra Nemcova, Jessica White, and actress Scarlett Johansson.
The Sweet and Lowdown actor was last linked to 27-year-old producer Shannon Costello, who served as the former communications director for Penn’s J/P Haitian Relief Organization, but the pair split in September 2011.
Meanwhile, Sean’s ex Robin has been dating her 32-year-old toyboy Ben Foster since February.
And his other ex Madonna, 54, has been keeping herself busy with 25-year-old French dancer Brahim Zaibat for the past two years.
Penn will next be seen alongside Ryan Gosling and Emma Stone in the long-delayed crime-drama, Gangster Squad, due out January 11.
Sean’s ripped bod does not appear to be for a role as his next two film projects will have him behind the camera.
He’ll soon direct Josh Brolin in the drama Crazy for the Storm, and he’ll also direct Robert DeNiro and Kristen Wiig in The Comedian.
