The Black gay singer took home Best Music Video and Pop Duo/Group Performance for his massive country hit "Old Town Road" with Billy Ray Cyrus.
These awards were announced in a ceremony several hours before the televised Sunday event on CBS. "THANK U TO EVERYBODY!! I AM NOW GRAMMY AWARD WINNING ARTIST LIL NAS X !!!" the singer wrote on Twitter following the win, along with several trophy emojis.
He later deleted the social media posts in respect of Kobe Bryant, the NBA legend who died in a tragic helicopter accident earlier in the day.
In a follow-up tweet, Lil Nas X said he "didn't mean any disrespect to kobe with that announcement. the news made me sad too! sending love to those grieving."
Lil Nas X is one of the most-nominated artists at this year's Grammy Awards. He received six nods, including Album of the Year and Best New Artist.
The gay artist also won the evening's red carpet; he arrived at the Staples Center in Los Angeles sporting a pink custom Versace ensemble referencing both kink and cowboy culture.
