One of the celebrity contestants on “Splash,” the ABC reality competition where participants try to dive from a high platform, has left the show. USA Today reports that former Playboy Playmate Kendra Wilkinson walked off because she was unable to overcome her fear.

“She walked all the way up. She looked cute in her suit. And then she freaked. When it came time to dive, Kendra Wilkinson couldn’t do it,” the story reports. “On Tuesday’s ‘Splash,’ the reality show star helped out her teammates by walking back down from the 23-foot platform, tears in her eyes. That was the only water she was touching.”

Wilkinson said: "I’m so sorry, everybody. It’s bittersweet. One thing I don’t do is quit. This is the first time in my life I’ve quit something. This will haunt me for the rest of my life."

“Kendra was paired with extreme skier Rory Bushfield, who had been advised by doctors not to compete after he ruptured an eardrum in practice,” the report notes. “She has been open about having a serious fear of heights.”

Wilkinson has commented about her problems with heights: "I start spinning, I start wanting to throw up, I’m shaking, my fingers wiggle.”

After Tuesday’s show, she tweeted: "Damn I got a lot of hate tonight but ill take it. Big mistake signing up for the show. Sorry I let you all down."
