On Sunday, Rob Kardashian posted a cryptic tweet about having a 6-year-old son, Just Jared. Jr. reports.

"I'm about to go pick up my Son from the port and can't wait to watch a great movie with him ,, Suggestions anyone ??? He's 6″ the 27-year-old reality-TV star wrote on Twitter.

Rob's cryptic tweet has since been deleted.

Although the Kardashian family has yet to confirm or formally announce that Rob has a son, media outlets such as Woman's Day, RadarOnline, and more suggest that Rob may in fact be a father.

"For the second time this year Rob Kardashian has mysteriously tweeted about having a son," reads a RadarOnline report.

Back in July, Rob tweeted then deleted a series of posts claiming that he was spending Independence Day with his alleged son, Woman's Day reports. 

"Can't wait to watch fireworks with my little man!," he wrote at the time.

Soon after deleting that post, Rob retracted his statement by posting another tweet claiming that he was joking about being a father.

"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" he tweeted.

Woman's Day notes that Star Magazine reported earlier this year that Rob admitted to having a son to his friends.

"The sock designer admitted to being a dad when friends noticed a teddy bear on his bed during a catch-up at his apartment," the Woman's Day article reads.

It continues, "The insider went on to claim that Rob's love child was the result of a fling with a woman he met in Miami a few years back."

Rob Kardashian has made no mention of a child since deleting his tweet last Sunday.
