Rihanna ... talkin' trash!!
Didn't take RiRi long to go in on Steph Curry after Game 7 -- throwin' a little shade at the NBA's regular season MVP on Instagram.
Rihanna's a HUUUGE LeBron James fan -- and overloaded her social media with tributes to King James after the Cavs took the title ... even calling him "Bae" at one point.
It's good to be the champ.
