Jada Pinkett Smith is pissed off about “All Eyez On Me” and how it portrays her relationship with Tupac … calling the movie, “deeply hurtful.”

Jada, who clearly just saw the movie, is taking issue with several scenes, including one where Pac reads her a poem. She says, “I didn’t know that poem existed until it was printed in his book.”

She also says they never fought backstage at any of his shows … as they do in the movie.

Jada and Tupac met in high school in the mid ’80s. She’s described him as one of her best friends, and although they kissed once … she says it was never a romantic relationship. Jada was even the inspiration for some of his poems that were published after his death.

She does praise Demetrius Shipp and Kat Graham — who play Pac and Jada — for their performances … but definitely shades the screenwriter.
