The reality TV star and brother to Kim, Khloe and Kourtney Kardashian, has struggled to shed the pounds in the past and is now considering reappearing on the show, on which he came runner up in 2011, to get into shape.

A source claims producers of the dance competition have even offered Rob, 28, the chance to hang out with this year's winner Rumer Willis and contestant Charlotte McKinney.

They told Radar Online: "Rob's been given an open invitation to visit the show and producers even dangled the prospect of serious hang time with Rumer Willis and Charlotte McKinney.

"He's back on his diet and has already lost several pounds.

"Rob hasn't ruled it out. The happiest anyone ever saw this kid was when he was dancing every day."

Meanwhile, the sock designer is said to have become increasingly frustrated with his family in recent weeks and believes they used his personal "issue" to keep their 'Keeping Up With The Kardashians' ratings high.

Rob is said to have felt "betrayed" by his sisters when they openly discussed his problems on the E! Series, with his mother Kris Jenner.

An insider previously said: "Rob feels betrayed that his mom and sisters discussed his issue on the last episode of 'Keeping Up With The Kardashians'.

"He's angry that his personal challenges have been minimised to mere high ratings for the show."
