Prancing Off The Pounds! Rob Kardashian Considering Making 'Dancing With The Stars' Return In Order To Lose Weight

Troubled Rob Kardashian is ready to two-step his way back to a healthful lifestyle!

RadarOnline.com can reveal that the youngest Kardashian is back on his dancing diet and he's mulling over a possible one-night-only return to Dancing With The Stars.

"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," an insider tells Radar.

So will he or won't he do the show? "Rob hasn't ruled it out," notes the insider, who hopes Kardashian goes for the opportunity because "the happiest anyone ever saw this kid was when he was dancing every day."

Like a true Kardashian, however, the 28-year-old has his eye on the potential payday, and he's holding out for a cash offer in the region of $50,000, reveals the insider.

However, "Rob will only go on the show if he drops some weight first," since, at 5'10" tall, "he's not a tall guy so when he puts on ten pounds it looks like twenty."

Adds the insider, "He's back on his diet and has already lost several pounds."
