TV personality Rob Kardashian is reportedly "bombarding" model Cara Delevingne with text messages.

Now, Delevingne reportedly regrets giving her number to the 27-year-old, reports femalefirst.co.uk.

"He's been bombarding her with text messages, and it's creeping her out. She's not attracted to him at all and is pretty insulted that he would think he had a chance," a source told Star magazine.

Meanwhile, Rob is struggling with depression after gaining weight and is struggling to cope up with news of his step-father Bruce Jenner's transition into a woman.

"He's still in a downward spiral. He's so lonely and desperately wants to find the right woman, but his confidence is at rock bottom. He really wanted Cara to like him," the source added.
