oprah*TMZ‘s 24 hour efforts to stalk celebs has paid off again.

Wednesday night, one of their paps caught up with the Queen of media, Oprah Winfrey, and summoned up the cajones to ask about her interview with Bobbi Kristina

Oprah, if you have heard, has come under fire for letting the Houston family off the hook … especially when Whitney’s sister-in-law suggested the singer was murdered.

But O told us, “I think it went really well … I think people really responded and I think the whole country now got to see how [Bobbi Kristina] feels and what shes going through.”

Oprah says she was SHOCKED people criticized the interview … but explains why she won’t let it bother her.

Also, Lady O was asked what’s the best way to dump a significant other … and she had a GREAT answer.
