"This has been one of the best things to ever happen to him," mama Kris Jenner recently told us while promoting her new memoir, Kris Jenner...and All Things Kardashian (out today).
"He's grown up in so many ways," she continued. "His maturity level and the way he handles himself and the way he feels about himself. It's a boost to his self-esteem, just being out there and doing something on his own. Not being told what to do all the time and sort of living in the shadow of his sisters. He really shines on his own and his personality really came out."
So would Jenner ever follow in Rob's footsteps and consider a gig on DWTS herself?
"Probably not," she said. "My schedule is just so crazy. I just don't think that it would be fair to my family because I'm their manager, for me to take off that amount of time."
"I would love for Bruce [Jenner] to do it," she said. "I don't know if he's a good dancer, but he would certainly enjoy the experience. He's always wanted to do it."
