*We think it’s safe to say that the young lady pictured above is not RayJ‘s cup of tea … by no stretch.

We say that because he didn’t mince any words when he used Instagram on Friday to compare her to a character from the “Planet of the Apes” films.

“I usually don’t go this hard but … This chick look exactly like a character on Planet of the Apes.”

Yep Ray J, you definitely went hard on the woman.  And the woman, Tina Chastang, told TMZ, she was mortified when he singled her out on his page.

Now, you may be wondering what would make Ray J go hard on this woman. What did she do to incur his wrath? It seems Ms. Chastang is admitting that she pushed one too many of Ray J’s buttons by posting inflammatory comments on his Instagram such as …

“Ray J you are irrelavant. Why dont you stop worry about Kim Kardashian. Why dont you talk about you being gay.”

Now that she’s the recipient of his fire power, she’s crying foul … that he doesn’t fight fair.

Tina’s rationale is that she’s just one voice out of millions of fans — thousands of whom trash talk Ray J on the daily — but he made a mockery of her on a global scale. Tina wants an apology.

“This girl is an Instagram bully,” sources close to Ray J tell TMZ. “She’s been making negative comments on everything Ray J posts for months. He’s been trying to take the high road, but finally decided he needed to give her a taste of her own medicine.”
