Holly Madison "gets mad" when she sees Hugh Hefner's new girlfriends.
The blonde beauty - who used to be one of the Playboy mogul's lovers - has accused Crystal Harris and twins Karissa and Kristina Shannon of copying her and the other ex-girlfriends, Kendra Wilkinson and Bridget Marquardt with their antics in 'Girls Next Door' - the show which follows the antics of the inhabitants of the infamous Playboy Mansion.
Holly said: "I had a great time with Hef and the girls when they came to see 'Peepshow' and hang out in Vegas. I don't watch the other episodes though, because it kind of makes me mad. The girls need to focus on what makes them unique and not doing the same things Bridget, Kendra and I have already done on the show.
"Even camping in the backyard was an idea I had for an episode that we never got around to shooting. And guess what they just showed? The girls camping in the backyard. I don't want to look behind, I want to look forward."
Holly is currently staring in Las Vegas burlesque show 'Peepshow' and says her 83-year-old former lover was impressed by her performance.
She told Fox News: "Hef really liked the show, but I knew he would. He loves burlesque and the girls in the show are really beautiful."
