Rob Kardashian is reportedly exerting a huge effort in trying to lose weight this 2015.

Other than health reasons and bringing back his self-esteem, Rob Kardashian reportedly has a specific goal in mind - to impress his mom/slash manager, Kris Jenner, so that she would hire her back to star in "Keeping Up With The Kardashians" this 2015.

"Without his reality TV paycheck and lack of gigs rolling in - Rob was relying mainly on handouts from his family," Celeb Dirty Laundry reported.

"But, Kris grew tired of supporting him and financially cut him off. The momager insists that she did it for Rob's own good - but what she doesn't admit on TV or in interviews is that she used to have a conniption every time the paparazzi got a snap of obese Rob, and was basically embarrassed of her own son."

Will Rob Kardashian lose enough weight to make it to the taping for the next season of "Keeping Up With The Kardashians"?

It has been previously reported that Rob Kardashian's former brother-in-law, Lamar Odom, also wanted to get back into his NBA physique before 2015 ends, and he allegedly encouraged Rob Kardashian to take the challenge with him.

"Lamar and Rob had a special bond when Lamar was married to Khloe and Rob was crushed when they got divorced, but that brotherly love never went away," an insider told Dish Nation.

According to the insider, Rob Kardashian's sister and Lamar Odom's ex-wife, Khloe Kardashian, approved of the former NBA player's idea.

After all, both Rob Kardashian and Lamar Odom have been through a lot these past few years, and 2015 could be the year they both get up from the slump.

"Khloe is 100 percent on board with Lamar's plan. She adores her brother and knows how much he loved Lamar," the source added.

Rob Kardashian has been avoiding the public eye amid purportedly suffering from depression and weight gain. It was allegedly Rob's decision not to participate in "Keeping Up With The Kardashians" for the past few seasons.
