Oprah Winfrey -- Terrence Howard 'Misbehaved' With My Big Breastses!

Oprah herself says don't hate on Terrence Howard for loving on her "tig ol' bitties" -- because she fully admits her rack was large and in charge during their sex scene.

Oprah taped an interview with Steve Harvey ... and talked about the scene Terrence made famous last week by blabbing about her round mounds.

Oprah told Steve ... "It was supposed to be like a little scene, and because Terrence Howard misbehaved it turned into a bigger scene, and then a bigger scene."

Can ya blame him?

As for people being offended about Howard's "tig ol' bitties" comment -- Oprah had an awesome response for that.
