A new report has indicated that Rob Kardashian has a secret son. 

According to Star magazine, the 26-year-old Keeping Up With The Kardashians reality star is holding a huge secret about a hidden love child. 

A source told the publication that the only Kardashian brother spilled the news at a recent gathering at his apartment when friends questioned him about a teddy bear on his bed. 

"He said that it was a present for his son," the source said.

"The possibility that Rob may have a child has been the buzz in the Kardashian circle for a while, but no one knows for sure. And no one will talk about it," another source added. 

Radar Online pointed out that Rob hinted at having a son back in May when he posted an Instagram noted that read, "Shout out to God ... Shout out Mom, shout out to my son's mom cuz she been holding me down since high school n shout out to my son Robert the Third. lol." He quickly deleted the post. 

Sources revealed that Rob told close friends that the child is a result of a romance he had with a Miami woman four years ago. 

"There's a good chance that the child's mother wants nothing to do with the fame, and that's why she's staying so hush."

Meanwhile, Rob has been keeping a low profile after he gained over 50 pounds from depression and dealing with an emotional breakup from singer, Rita Ora. 

Earlier this month, he revealed his plans for losing the weight, saying that he is currently taking supplements and working out twice a day. 

"All I'm just trying to focus on is my health and just getting back to that happy point," he told Entertainment Tonight. "I feel like people see a lot of unhappy points, which is not me. I just want to get back to the good points. I'm 26 years old; I'm supposed to be enjoying my life."
