This isn't related to the Roloffs, but just a quick post because some readers were asking just to make sure, or for anyone interested, since we have frequently reported on some of Jen Montzingo's on blog topics that are discussed here and Jen was kind enough to respond to comments and some rather nasty criticisms of her by some posters to our site a couple of months ago.
So yes, that is indeed Jen Montzingo's brother, Peet on the new show with Simon Cowell -- X Factor USA.
In one of her videos explaining that she was always interested in becoming an actress or a career in Hollywood, she referenced that one of her brother's had no interest in it, while the other shared her dream. That brother is now on X Factor -- Peet Montzingo.
In this clip about his audition on X Factor, they discuss Peet being the only average height member in his family.
