LeBron James -- 'Perfect Booties' Model Revealed ... 'It's a Sign From God'

The woman whose butt was on the receiving end of an Instagram "Like" from LeBron James this week says the NBA star has changed her life forever ... calling the whole thing "a sign from God."

Josett Latrice became an overnight sensation when LeBron broke his self-imposed social media ban (implemented so he can focus on the NBA playoffs) to "like" one of her pics on the @perfectbooties Instagram account.

"It makes me feel awesome," Latrice told "TMZ Hollywood Sports" ... "I LOVE the fact he liked my picture."

Josett has been studying to be a veterinarian -- but says now that she's got Bron's stamp of approval, she's considering taking serious steps to focus on modeling instead.

"It's definitely a sign from God."
