Lil Nas X is applauding Dwyane Wade and Gabrielle Union for supporting their 12-year-old kid who is now identifying as female ... and he's also got some advice for Zaya.
The "Old Town Road" singer, who came out last year, weighed in on Zaya's big announcement Wednesday at LAX ... explaining why it's important for kids to have parents in their corner when they reveal their truth.
As you know ... the NBA legend appeared on "The Ellen Show" Tuesday and told the world his kid identifies as a female after being born male.
