Lil Kim's baby father has finally been revealed, and he's not boxing champ, Floyd Mayweather.

Days after Kim announced her pregnancy at a show during New York Fashion Week, many wondered who the baby's daddy was, after she didn't immediately reveal his identity.

Rumors started to swirl that there was a possibility that Mayweather could be the unborn child's father after the couple dated last year. When Mayweather defended his light middleweight title against Saul Alvarez on Sept. 14 in Las Vegas, Kim was there by his side, despite the champion being engaged to Shantel Jackson.

"They are the best of friends and have dated," a source close to the 39-year-old rapper said.

But Mr. Papers, Kim's ex-boyfriend is said to be the father after he replied to a tweet congratulating him. He also fueled rumors that Kim is expecting a baby boy.

"Congratz on the royal baby!" a tweet read to Mr. Papers, in which he responded, "royal is good name for the lil homie."

Mr. Papers even took to Instagram to write, "I heard everybody looking for me ?????????????????"

A source told Confidenti@l that Kim is 4 1/2 months pregnant, and one reason why she has been secretive about her pregnancy is because she is gearing up to start filming a reality show in March.

Meanwhile Kim told Us Weekly that pregnancy won't get in the way of her career.

"I'm still going to work," she said. "I'm still going to be hardcore. The baby has made me even more of a beast!"
