He's 76 years old but Charles Manson is still quite the lady killer in fact, Charles got an early Valentine's Day prison visit from a special female.

TMZ is reporting that officials at California State Prison say the visit occurred on Sunday morning (the day before V-Day) because no visitors are allowed during the week.

We're told Manson is "very choosy" about who he meets with and rarely accepts visits but for some reason, he gave the green light to spend time with a certain lucky lady. Officials wouldn't reveal the woman's name.

Who would go visit him?
