'Overweight & Depressed' Rob Hides From Cameras At Daughter Dream's Birthday Bash

Khloe, Kourtney and Kim Kardashian posted sweet photos of their niece Dream's lavish 2nd birthday party last night — but fans noted that the little birthday girl's dad Rob was nowhere to be seen. Now, RadarOnline.com can exclusively report that the famous family's black sheep brother did indeed attend the bash, though he hid from all the cameras.

"He is overweight and depressed," a source close to the clan told RadarOnline.com of the 31-year-old fallen sock designer, who is in the midst of a nasty legal war with his baby mama Blac Chyna. "It's bad. The family is very worried."

As RadarOnline.com exclusively reported, Rob declared in court papers that he's $300,000 in debt, and claimed he nearly lost his company Arthur George due to his battle with ex Chyna, 30. In documents, momager Kris Jenner said she helped save the company by investing money.

"It has been an extraordinary difficult time for me emotionally," Rob told the court.

Now, the worried family doesn't know what to do about Rob, who has been struggling with depression and his weight on and off for years.

"They've given up trying to fix him," the source said, adding that Kourtney is the only sister in constant contact with Rob.

Rob is desperately trying to lower his $20,000 a month child support payments to Chyna, claiming he simply can't afford to keep it up.

Chyna's lawyer slammed the celebrity brother as a "poor little rich boy" who is slinking out of his responsibilities.
