Rob Kardashian is once again fueling rumors that he might have a secret son. For the second time in the past few months, he has hinted on having a son living elsewhere in the U.S.

The Hollywood Life reported that the 27-year-old has been sending mixed signals to his fans through posting Twitter messages that could be easily misconstrued. In a rather confusing manner, Rob has posted a Tweet that hinted on him having a secret child. His messages keep confusing his fans as he denied the existence of a son himself.

His latest confusing Tweet was posted on September 18.

Was with my baby mama tonight ,,

It is not clear whether Rob is actually referring to the mother of an unknown child he has possibly fathered or it is just a slang to refer his current flame. No information had been released from the Kardashians as well.

In July this year, a mysterious Tweet surfaced on his account where he claimed to be eagerly looking forward to July 4 because he'd be enjoying the fireworks with his son. The post shocked his 5 million followers. However, the Tweet was eventually deleted quickly and Rob merely laughed off the incident, claiming it to be just a joke.

Known for his appearances in the reality show 'Keeping Up With The Kardashians', the American businessman and model also starred and won second place in the 13th season of 'Dancing With The Stars'. A self-proclaimed passionate socks designer, Rob owns a line called 'Arthur George'. His earlier relationship with actress Adrienne Bailon lasted for four years, followed by a brief fling with Rita Ora.

While various media critics are reportedly discarding his recent Tweets as another publicity stunt, the mother of the reality TV star urged the family to focus more on Rob's health issues. His recent weight gain is a major source of concern for Kris Jenner and the rest of the Kardashian clan. News.com claims that Rob is reportedly struggling with depression and weight gain amid rumor of alleged drug abuse.
