Rob Kardashian has surprised fans by referring to "his son" on Twitter.
The 27-year-old reality TV star shared his happiness at spending the Fourth of July with his "little man".
"Happy I got my Son with me for the 4th tomorrow !! Can't wait to watch fireworks with my little man ! Hope everyone is safe ! X."

Just hours later, the message was deleted from the social sphere, and the TV personality wrote: "Those who know me know I play and I do NOT have a Son. Y'all got my mama emailing me asking if I have a Son lol goodness hahaha. GOODnight."
Rob's Twitter fun comes amid continued rumours that he has fathered a child. In June he also joked about being a father, writing: "And to my baby mama I loveeeeeeee you."
The Keeping Up with the Kardashians star's behaviour on social networks has been somewhat erratic of late.
He tweeted a cryptic message in June – "no one will ever understand how much it hurts" – which he went on to delete, before "unfollowing" everyone except his mum Kris Jenner and sister Kylie.
Karadashian matriarch Kris spoke out recently, admitting that he is "struggling with some stuff".

Speaking on E! News at the beginning of June, she said: "Rob is living in LA right now, he is doing well, finding out what makes him tick. He is struggling with some stuff but my job is to be there for him and love him as hard as I can.
"Everyone goes through stuff and we get through each other's adversity one year at a time."
