Is Rob Kardashian Stalking Cara Delevingne?

It seems that Rob Kardashian has a huge crush on his half sister's friend, model Cara Delevingne, but she doesn't seem to like him back.

According to Fashion and Style, Rob has been sending too many text messages to Kendall Jenner's friend. The site claims that Star Magazine revealed that Rob has "been bombarding her with text messages, and it's creeping her out."

The source added, "She's not attracted to him at all and is pretty insulted that he would think he had a chance."

Rob has rarely been seen out in public, or with his Keeping Up with the Kardashians family since opening up about his weight issues.

According to Hollywood Life, Rob has gained almost 40 pounds after he broke up with Rita Ora. Another of Rob's ex-girlfriends, Adrienne Bailon, is currently engaged, and it seems this Kardashian's love life has a lot to do with his depression and weight gain.

"It's crazy how this whole year, my whole relationship was only negative, all I did was gain f*cking 40 pounds and lose so much money," Robert said.

Last time we checked in with Rob he was busy claiming that a little boy was his son. This is how that rumored story went:

Back in July, Rob Kardashian tweeted about having a son, then quickly deleted the post. He later claimed to be only joking, but it was neither the first not the last time that Rob publicly confirmed that he's a dad.

Last year, Rob told friends he has a kid, shortly after posting a "shout-out" to his "son's mom" on Instagram. Yesterday, Rob tweeted, "I'm about to go pick my son up from the port and can't wait to watch a great movie with him...Suggestions anyone? He's 6." He quickly deleted the tweet, but did not post a "Just kidding!" retraction as he has in the past.

So why would Rob attempt to keep his offspring under wraps, and why would he so terrible at keeping it on the down-low? Addressing the second question first: Rob's struggles with drug addiction are well-documented. But why would he want to keep the kid a secret in the first place?

Rob, who deleted and added back his social media accounts, only has one photo on his Instagram page. The snapshot is a picture of his father, Robert Kardashian, whom he was named after, and himself with he was a child.
