In the family: Kim's younger brother Rob has a Kardashian butt

The 24-year-old, who's currently dancing his bum off on the US series of Dancing With The Stars, was spotted last week visiting the same manicure salon that his big sisters often frequent. And look at that money maker!

Rob has admitted that he's insecure about his weight, but we can't see what he's talking about — sure he's got a rather shapely derriere that doesn't necessarily do him the same favours that it does his sisters, but he looks pretty hot to us!

He said on the show, "To be in front of a bunch of people, knowing like, Ok, I'm insecure with my weight and I say I have man-boobs jokingly, but it's true.

"With all these dancers who are in great shape, it's just hard to be around and kind of put yourself out there like that."

Dude, you look fine!

Sounds like the poor guy doesn't really want to be in the spotlight. After all, he says his mum Kris Jenner "pretty much forced" him to take part in Dancing With the Stars. Can you say 'stage mum'?
