The 30-year-old singer tweeted at Frank Ocean in regard to his criticism of the awards show.

Solange Knowles decided to react to Frank Ocean's GRAMMY criticisms just moments after her older sister, Beyonce, lost out to Adele for Album of the Year.

On Sunday night, the 30-year-old singer retweeted Ocean's Tumblr rant against the awards show, along with the message: "Wuddup Frank."

In the post, Ocean defends his decision to skip the GRAMMYs after the show's producer, Ken Ehrlich, and writer David Wild criticized his "faulty" 2013 GRAMMYs performance in a recent interview. While the 29-year-old singer admitted that he was interested in participating in the Prince tribute, which Bruno Mars ended up performing at the GRAMMYs, he took issue with Taylor Swift's 1989 winning Album of the Year in 2016 over Kendrick Lamar's To Pimp a Butterfly.

"Hands down one of the most 'faulty’ TV moments I’ve seen," he wrote in reference to Swift's win.

While Knowles' cryptic tweet leaves room for interpretation, Adele outright declared that Beyonce's Lemonade deserved Album of the Year.

The 28-year-old singer brought Queen Bey to tears when she proclaimed, "I can’t possibly accept this award and I’m very humbled and I’m very grateful and gracious. The artist of my life is Beyonce and this album for me, the Lemonade album, is just so monumental. It was so monumental and so well thought out and so beautiful and soul-baring and we all got to see another side to you that you don’t always let us see and we so appreciate that.”

“And all of us artists here adore you,” she continued to cheers and applause from the audience. “You are our light and the way that you make me and my friends feel, the way that you make my black friends feel is empowering and you make them stand up for themselves. And I love you. I always have and I always will.”
