Not all celebrities like to keep their private lives under wraps — in fact, some have a tendency to over share, especially when it comes to details about their sex lives. And no, we're not just talking about sex between two people, plenty of celebs have had threesomes and are spilling the deets.

Amber Rose had her very first threesome at the end of last year, and she didn't skimp on the details. "We kinda just got together, it was a guy and a girl and it was f–king horrible," she admitted. "It was the worst. It was horrible. I am literally having sleepless nights. I felt the pressure, getting older, to experience new things and I did it against my better judgment because I talk about sex a lot."

"I hated it. Because I feel like I am a very passionate lover and I like that one-on-one passion. With the threesome I felt like there was no passion. There was no kissing and rolling around. All those moments were not there," she said.

Other stars like Lady Gaga and Chris Brown had a very different experience than Amber, as you'll see.
