The "Drunk in Love" singer recreated the cover of Braxton's 1993 single "Another Sad Love Song", posing in a white tank top with a black leather jacket slipping off her shoulders, just as Braxton did 25 years ago.
Beyoncé wore her hair in a short pixie cut that mirrors the singer's 'do back when the single was first released. She even gave herself a new moniker for the occasion, making her debut as "Phoni Braxton".
"Sending love and adoration to one of our talented legends. Thank you for the countless bops," Beyoncé wrote on Instagram next to a photo of her Halloween costume. "Your tone, your beauty, your range, and your God-given talent is treasured. Loving you always. Have a Happy Halloween my Kings and Queens."
Beyoncé also posed for her own version of the cover of Braxton's 1993 debut album, simply titled "Toni Braxton". The image shows more of her costume, which also includes a pair of jeans and three gold chains wrapping around Beyoncé's hips – a close recreation of Braxton's early-1990s look.
Braxton was impressed with Beyoncé's tribute and showered her with praise on Twitter.
"Phoni Braxton!? NEVER!!!" the singer wrote. "How do you look better than me on MY album cover? I LOVE IT, Such a superstar! Thanks for the love sis! Happy Halloween."

She then referenced one of Beyoncé's hits, adding: "Who run the world...GIRLS! GIRLS!"
This isn't the first time Beyoncé has channelled a cultural icon for Halloween. In 2016, she made headlines by dressing up as the hip-hop trio Salt-N-Pepa along with her daughter Blue Ivy and her mother Tina Knowles. Two years prior, she went as Janet Jackson while Blue Ivy dressed up as Janet's brother Michael.
