Usher and Ne-Yo attended Usher’s Past Present Future Tour after-party at “Ladies Love R&B” in Atlanta on Wednesday, Dec. 11.

Other stars in the house included Summer Walker (left), Teyana Taylor (right), Skilla Baby, DJ Infamous, DJ Holiday, and Sincerely Ward.

Usher congratulated Ne-Yo on making polyamory work for him. Singer/songwriter Ne-Yo is enjoying life as a single dad with three beautiful girlfriends at home.

Unlike most men who are in committed relationships with one woman, Ne-Yo is free to “cheat” with his three girlfriends. He gets the emotional support he needs from more than one woman. And they all share responsibilities around the home.
