Britney Spears received star-studded support during the opening night of her Las Vegas "Piece of Me" show on Friday.
The pop princess had all eyes on her (including some famous ones like Miley Cyrus, Katy Perry and Selena Gomez) at the Planet Hollywood Resort & Casino as she kicked off her two-year residency in Sin City.
Spears, 32, who had seven different eye-popping costume changes and two different wigs, wowed the crowd by performing 23 of her chart-topping songs.
Miley Cyrus dances with Britney Spears' mom, Lynne, at her first Vegas show as they watched Spears on stage.
The "Work B**ch" singer's mother Lynne and sister Jamie Lynn were also among the concertgoers there to cheer on their girl.
Spears' family sat next to Cyrus, who was standing up throughout the entire show singing along to Spears' iconic hits.
While there was no sign of twerking, the fellow pop star was certainly breaking it down to the music.
Perry was spotted saying hello to Cyrus, but also appeared to be sitting alongside Gomez in a different section.
