“Desperate Housewives” co-star Nicollette Sheridan is apparently a bit of a head case… according to her ex-fiance Niklas Soderblom in his book, Desperate Houseman.

Soderblom maintains that Sheridan was so worried about getting dumped from the show: “It was a competition. She was a middle-aged woman in Hollywood and deep down I am sure she sees Desperate Housewives as her last big break.” He recounts one time when “she was devastated when the posters for the show showed the other four women, but not her. She started crying. She said she was sure the producers intended to ditch her character. She exploded. She screamed ‘Don’t you get it? Haven’t you seen the posters? Teri, Marcia, Felicity, Eva… but no Nicollette. Do you get it? No Nicollette. They don’t give a s— about me. It’s like I don’t exist.”

Hmm. How much here is reality and how much is to sell books?
