An ex-Kardashian bodyguard has legally changed his name to Bruce Jenner to preserve the name’s “heterosexual roots.”

The Florida man, formerly known as Mark Behar, says he doesn’t want people to associate the name with the Kardashians and Caitlyn.

“This name once stood for America, and I just want to keep it alive,” Jenner told New York Daily News. “I’ve been seeing so many idols and athletes and icons die because of stupid stuff like drugs, die because of age … We’re losing icons. We’re losing names. We’re losing people faster than we ever have.”

“I am not anti-gay and I have no problem with him changing his sex, but the way he did it, in my mind it was not proper. It was all for hype,” Jenner continued.

“If Caitlyn ever wants to be called Bruce again, he’s a day late, a dollar short. It’s my name now,” Jenner says.

Jenner worked as a bodyguard on “Keeping Up with the Kardashians” in 2009 and 2010. He appeared in one episode in season four where he and Caitlyn participated in a charity boxing match before her transition.
