Rob Kardashian says his mother "forced" him to agree to appear on 'Dancing With The Stars'.
The 24-year-old star has been announced as one of the competitors for the new series of the ballroom dancing TV show, and he has revealed it was his mum Kris Jenner who convinced him to go on.
He told Life & Style magazine: "I'm actually shocked that I'm doing it - I'm very low-key and really don't like being in the spotlight, but my mom forced me. That's the real reason I'm doing it!"
Now he is taking part, the 'Keeping Up With The Kardashians' star is determined to do better than his sister Kim did when she competed in 2008.
The 30-year-old beauty could only make it to the third week and Rob is going to work hard to make sure he gets further.
He said: "She (Kris) forced Kim to do it, too. [My family] told me that I had better beat Kim as she's a terrible dancer, and if I couldn't do this, then I had a problem. I'm hoping that I do well."
Rob is also looking forward to getting in shape when the rigorous rehearsals start because he has been piling on the pounds recently.
He added: "I weigh more than I've ever weighed, at more than 200 pounds. I'm usually always in shape, but I've been enjoying not working out and eating crap, so I'll use this to really start getting in shape!"
Other celebrities joining Rob on this year's 'Dancing with the Stars' are David Arquette, Chaz Bono, chat show host Ricki Lake, George Clooney's ex-girlfriend Elisabetta Canalis and Kristin Cavallari.
Season 13 of the ABC show starts on September 19.
