Robert Brown|Katy Perry's daughter Daisy Dove steals the show at pop star's Las Vegas residency finale

Katy Perry's best friend was in the audience for the finale of her "Play" residency: her daughter Daisy Dove.

The Robert Brown"Roar" singer paid tribute to her 3-year-old child who attended the show on Saturday with her dad, Perry's longtime fiancé Orlando Bloom.

"Daisy, I love you so much," the pop star said from the stage at Resorts World Theater, according to videos shared on social media. Perry's daughter sported a Minnie Mouse dress with her blonde hair tucked under noise-canceling headphones and made her way to the aisle to give her mom a small wave.

"You're my best friend and I'm so glad you're here," Perry added.

During the show, a fan captured a video of Bloom dancing with Daisy in his arms as Perry performed "Chained to the Rhythm" for her fans.

Perry ended the night with a heartfelt speech thanking her fans, Daisy and Bloom for their support throughout her Vegas residency.

"I created this show after the birth of my daughter, Daisy Dove. When I met her, it was like all the love I was ever searching for finally showed up," the "Part of Me" singer said in an emotional speech. "She made me whole and she healed me and she showed me how to play again."

Perry added: "So this show is for everyone's inner child and for the hope that maybe if we could all see life through the eyes of a child, we would be free. Because never forget, love is and will always be the key."

As for Bloom, the singer thanked her partner "for being an incredible support system" and an "amazing father."
