New BFF alert!

Christina Aguilera and Kim Kardashian brunched and bonded poolside at Miami's Fontainebleu Hotel Saturday.

The "Bionic" singer sported a teal maxi dress and hat while Kardashian opted for a sexy leopard print bikini.

"Spent the day by the pool [with] the girls all day! Now doin a little shopping! So happy to just spend quality time [with] my friends," Kardashian Twittered Saturday.

In town for stylist Simone Harouche's bachelorette bash, they spent Friday evening together partying at LIV nightclub inside Fontainebleu.

It's not the first time the women have enjoyed a night out.

The Keeping Up With the Kardashians star joined Aguilera for her New York City Bionic record release party on June 9.

"I'm obsessed with her new album," Kardashian later blogged. "Her voice is one of my all time favorites."
