Prince responded to a fan who recently attacked him on twitter writing, "everyone knows you are a Rowe-Klein NOT a Jackson!!"

"The blood of the covenant is thicker than the water of the womb ... I was raised by my dad with my brother and sister," he replied the Twitter user. Making it the closest he's ever come to saying MJ isn't blood -- but it also makes it clear Michael is the only father he's ever known.

Over the years, there have been a lot of rumors claiming MJ's longtime physician and friend, Dr. Arnie Klein fathered Michael's kids with Debbie Rowe. Klein added fuel to the fire in 2013 when he compared an old driver's license pic of himself to one of Prince.

But according to TMZ, Michael is NOT Prince's biological father ... and neither is Arnie Klein. Dr. Klein passed away on Thursday, October 22 from Multiple Sclerosis.
