Demi Moore is getting real in her upcoming memoir “Inside Out” – as in, real enough that her ex Ashton Kutcher apparently “freaked out” when he found out what she spills in the tell-all. Now, we know what the fuss is about.

RadarOnline has spilled some of the details… in the book, Moore reveals that she and Kutcher tried introducing a third party into the bedroom a few times, and she regrets it. Why? All was good at first, but soon things started getting a little fishy. Once things took a bad turn, Moore says Kutcher used their experimentation as a defense of his alleged infidelity.

Basically, Kutcher told Moore not to come to the set of his steamy movie “Spread,” saying his female co-star wasn’t comfortable with the idea. Turns out she actually was, Kutcher wasn’t being honest… particularly about his sex life. Moore tried experimenting with him to “show him how fun I could be,” but he ended up blaming the “blurred lines” for his cheating later.
