Rapper 50 Cent has announced that he has a third son whom he has apparently never met.

The In Da Club star posted a picture on Instagram of him with a young boy at what looked like a meet and greet event.

“My life is full of surprises, this little guy is my son DAVIAN. He started crying, I was thinking why you crying i gotta pay for this s**t. LMAO,” he wrote.

50, whose real name is Curtis Jackson, followed it up with a picture of what seemed to be a letter from a teacher singing Davian’s praises.

He wrote: “I JUST GOT THIS, ? DAMN I NEVER DID This good. This kid is smarter then a motherf****r !!! I’m a get Big Floyd to give him some hands.”

A third image looks like a modelling shot, showing the boy posing in a hat with a jacket thrown over his shoulders.

50 captioned that one: “This is Davian doing his, I’m cooler then my dad look. ? Talking about meet me at Red Stix. LMAO.”

The 40-year-old star – who already has two sons from previous relationships – hasn’t revealed who Davian’s mother is.

While his posts about his new son seem to be serious, some outlets are speculating that they might be part of one of 50′s pranks.
