Being blond, busty and beautiful apparently isn't all it's cracked up to be.
Former Playboy model Holly Madison says that beneath her Barbie-doll measurements beats the heart of an insecure woman who used plastic surgery as a way to build her self-esteem.
And she blames ex-boyfriend Hugh Hefner for that lack of confidence.
"Living with Hef brought down my self-esteem a lot," Madison told Life & Style. "I was comparing myself to the other girls ... You have to look a certain way at the mansion."
Madison, 29, one of a trio of Playboy models whose daily misadventures were the basis of the E! reality show "The Girls Next Door," also told the magazine her bosom isn't the only body part she had enhanced.
"Plastic surgery made it easier for me to get things I wanted in my career," she said. "Without it, I wouldn't be where I am today. My nose photographed really big in front of my face. If I wanted to do anything in the entertainment industry, I needed to get it fixed."
The sex symbol, however, does draw the line when it comes to certain artificial beauty aids.
"I'm scared of getting stuff (like Botox) put into my face," Madison claims. "It makes you look like you have a rubber mask on. Beauty is truly on the inside. Looks don't define you - they're just a tool to get what you want."
