Kelly Rowland talks Beyonce's 'Lemonade.'

Kelly Rowland couldn't be prouder of Beyonce's latest work of art.

ET caught up with the 35-year-old singer at Safe Kids Day 2016 in Los Angeles on Sunday, where she gushed about her BFF's headline-making new album and documentary, Lemonade, which dropped on Saturday night.

"I'm so proud of her," Rowland told ET's Lauren Zima. "She's just so transparent and it's beautiful music. I'm very proud of her."

And it's this transparency that has so many fans buzzing. Beyonce's Lemonade includes themes of infidelity, which left the Beyhive speculating about marital issues between her and Jay Z, especially when it comes to the song "Sorry" and its lyric, "Better call Becky with the good hair."

After designer Rachel Roy posted an Instagram message on Saturday night, reading, "Good hair don't care," some fans took it as evidence that Roy was Beyonce's "Becky."

"I respect love, marriages, families and strength," Roy tweeted on Sunday, after both deleting the Instagram post and making her account private. "What shouldn't be tolerated by anyone, no matter what, is bullying, of any kind."
