Sean Penn's alleged stalker has been arrested.

The unnamed woman was allegedly picked up by police in Malibu last week after she visited the home of the 56-year-old actor twice in two days.

TMZ has reported that Sean claims the 51-year-old woman had ''tried to contact him about 50 times this year by phone or email''.

The website also reports that during the woman's first visit last week the 'Dead Man Walking' actor was inside his residence and contacted the police at the time to file a report.

During the second visit, it was reported that someone else called the police and the woman was allegedly arrested for felony stalking. The website claims it is unknown whether or not the actor was at home at the time of the alleged arrest.

The woman is said to have believed she was in a romantic relationship with the 'Mystic River' star.

The day after her alleged arrest, she was released on $150,000 bail.

And the unnamed woman isn't the only one showing her affection to Sean either, as his ex-wife Madonna - who he was married to for four years before their divorce in 1989 - recently confessed she was ''still in love'' with the 'I Am Sam' actor.

Speaking to Sean on stage at a fundraiser in Malawi, the star said: ''I'm still in love with you. Yes. In fact, I think I love you more now that we're divorced.''

The 'Like A Virgin' hitmaker also professed her love for the actor at another benefit gala in January.

The 58-year-old singer said: ''I want to say, Sean, that I love you from the moment that I laid eyes on you and I still love you just the same. I just wish you'd stop smoking so many cigarettes.''
