Bree - who left Sober Valley Lodge in April - told Playboy magazine: "He's intelligent, he's charismatic, he's super
funny. He's good in bed. I mean, he's had a lot of practice. He's gentle and considerate in bed.
"He's just a rock star. He's a powerhouse. He's a very sensual and sexual person, and when I was with him I felt as if we became one together because he's just so enticing sexually."
Bree also denied claims she and Natalie - who has now also moved out of Charlie's home - had regular threesomes with the 45-year-old star.
She said: "That was a lie. I didn't really even know her. OK, all three of us got together, I think, twice. They did their thing together, and Charlie and I did our thing together. And we had two different beds. She and I would go to whichever bed, and he would pick. You know, 'Where am I sleeping tonight?' "
