Rumors about the paternity of Michael Jackson's children have been circulating for years, occasionally serving as a major source of stress for his family.
There have even been reports that Paris Jackson's 2013 suicide attempt was triggered by her realization that Michael is not her father.
Paris' older brother Prince, however, seems genuinely unconcerned about the identity of his biological dad - or at least he's come to accept it.
TMZ reports that a Twitter user recently raised the billion-dollar question of Prince's paternity by tweeting at the impressionable 18-year-old:
"Everyone knows you are a Rowe-Klein, NOT a Jackson!"
The names refer to Prince's mother, Debbie Rowe, and Dr. Arnold Klein - Michael's dermatologist friend and long rumored to be his kids' father.
Rather than telling the troll off or simply ignoring the comment, Prince Michael responded directly, and in curious fashion, tweeting:
"The blood of the covenant is thicker than the water of the womb ... I was raised by my dad with my brother and sister."
Hearing Prince address the rumors of his paternity for the first time is jarring no matter what, but especially in light of how he worded that.
Some are saying that that's Prince's way of confirming that he and his siblings are not Michael's kids, and it's easy to read it that way.
Whatever he means, it certainly seems as though Prince is very aware of the distinct possibility that he's not biologically a Jackson.
Klein, for his part, has done little to dispel these reports.
In addition to admitting on record that he once gave Michael sperm (seriously), he posted a side by side comparison of himself and Prince.
Debbie Rowe, Prince's mother, is famously private and unlikely to ever reveal the details of who inseminated her with Prince or Paris.
We have no way of knowing when Prince began having doubts, but we like to think he knew something was up the first time he attempted to moonwalk.
