It was a star-studded evening at Erika Jayne's The Pretty Mess Tour, as several of her Real Housewives of Beverly Hills costars showed up in support of the leggy songstress.
Erika rocked the house in a gorgeous and sparkly grey and black number at the Globe Theater in Los Angeles on Sunday night.
Kyle Richards, Dorit Kemsley and Lisa Rinna were all spotted in the crowd of her show.
It all looked like they were screaming "Hayyyy!" to Erika while she was on stage.
The celebration continued after the concert was over, where Erika hung out with actress January Jones and many more!
Kyle also chilled out with her handsome hubby Mauricio Umansky. They were two of the many cutie couples at the American Music Awards last Tuesday.
