Gabourey Sidibe did NOT hold back in grilling Raven-Symoné … asking why she treated her like she didn’t like her when they filmed “Empire” … and the awkward interview is on video.

Appearing on “Tea Time with Raven and Miranda” … GS flat-out admitted … “I didn’t think you liked me … I’m actually here like, what’s up?”

A bewildered Raven then asked … “Why didn’t you think I liked you?”

Gabourey fired back … “I was told that you made some people promise not to be friends with me.”

Raven then said she didn’t know her at the time … but Gabby said of their previous interactions in Chicago on the “Empire” set … “I felt like you were put off by me.”

Raven’s co-host Miranda Maday admitted — in front of Raven — that the “Raven’s Home” star could be petty, mean, and an a**hole, but defended her, saying that going behind someone’s back is NOT so Raven.

However, Raven said … “What I would say is, ‘Don’t bring her around me.’”
