The singer, who sent the tweets just hours before the highly anticipated release of her album Thank U, Next, is up for two awards this year: best pop solo performance for God Is a Woman, and best pop vocal album for Sweetener. "And I am not hung up on what happens or doesn't happen", she said.
The Grammys have also struggled with gender inequality, an issue that came to its head a year ago.
Janelle Monae remembers being frustrated last year, but this year she is looking forward to the show, where women are now leading in nominations for big categories like album of the year and best new artist. The nominations are dominated by Drake and Kendrick Lamar, with eight and seven nods, respectively.
Carlile is the most nominated woman with six nominations, including bids for song and record of the year with "The Joke". Cardi B, Kacey Musgraves, Brandi Carlile and H.E.R. also in contention.
Lady Gaga scooped up five nominations including for both Record and Song of the Year for her heart-pounding hit Shallow, which she performed in the film A Star Is Born with co-star Bradley Cooper.
The three-and-a-half hour extravaganza will feature performances from nominees Chloe X Halle, Grammy-winner Lady Gaga (choosing this over the Bafta film awards), fellow victor Mark Ronson and Grammy nominee Travis Scott fresh off his performance at Super Bowl LIII.
When asked soon after the show about the lack of female winners, academy president Neil Portnow said women needed to "step up" - now-infamous words that instantly drew outrage, and which he said were taken out of context. As far as performers go, fans of Ariana Grande might be disappointed to learn that she dropped out of the ceremony.
Check out our gallery of the red carpet arrivals from this year's Grammy awards! A study released by the University of Southern California's Annenberg Inclusion Initiative days before the ceremony found that of the 899 individuals who had been nominated for the previous six shows, 90.7 percent were men. The show kicks off tonight, February 10 - but before we see singers performing and winners being announced, we need to talk about the #FASHUN.
Drama has also surrounded the Grammys around its Motown Records tribute: Some people complained when a promo aired on CBS showing Jennifer Lopez as the act set to honor the legendary record label, which launched the careers of Jackson 5, the Supremes, Stevie Wonder, Marvin Gaye and more.
Some complained that a black artist should be involved in the tribute, while others said stronger vocalists should perform over Lopez.
The live ceremony in Los Angeles could see Cardi B take home her first ever Grammy and potentially become the first rapper since 2004 to win the coveted album of the year award for her "Invasion of Privacy".
