Jon Cryer opens up in his new memoir "So That Happened" that he dated Demi Moore years before Ashton Kutcher. Cryer and Moore dated after they co-starred in 1984's romantic comedy movie "No Small Affair". It turns out that Cryer dated Moore approximately 30 years before Kutcher did.

Cryer reveals that he had "awkward moment" with his former "Two and a Half Men" co-star, Kutcher. "It was awkward in that I'm not sure she even told him that we dated," Cryer says when he explains his meeting with Kutcher in the studio. Cryer was screening new actors to replace Charlie Sheen after Sheen departed from the CBS sitcom in 2010. "In our first meeting, we're trying to have that let's-create-that-chemistry meeting and the whole time I'm looking at him, waiting for him to drop the bomb," he recalls.

Kutcher was married to Moore at that time. They had been married for six years before finally divorced in November 2013. Cryer learnt that he did not have to worry, "At the end he said, 'She told me.' He was cool about it."

Moreover, in his memoir, Cryer admitts that he hired a prostitute shortly after his divorce from Sarah Trigger. He also suggested Sheen to call a hooker after Sheen split from his wife. However, he thinks that it is not a good idea if his 14-year-old son Charlie reads about it. "It's not the proudest moment of my life," he told ET.
