Dr. Robin Smith Says Michael Jackson, Whitney Houston Weren't Killed By Drugs (VIDEO)

In her new book Hungry: The Truth About Being Full, Dr. Robin Smith explores the path to finding fulfillment and true satisfaction. When Dr. Robin sat down with Oprah for an upcoming episode of “Super Soul Sunday,” airing Sunday, March 10 at 11 a.m. ET on OWN, the bestselling author, psychologist and ordained minister opened up about her personal experience with being emotionally and spiritually starving even when, on the outside, it looked like she had it all.

In this exclusive clip, Oprah says that Dr. Robin was not alone in feeling empty while in her prime. “I think this happens to everybody who has some level of success,” Oprah says. “[You call it being] ‘hungry for the high note.’”

“[In Hungry] I talked about Michael Jackson and Whitney Houston and their early deaths," says Dr. Robin. "People say that drugs killed them. Drugs didn’t kill them. What killed them is that they were striving and hungry. They were starving to hit the high note again.”

Dr. Robin explains, "Whitney said [to Clive Davis] right before she died, ‘I’m going to hit that note again.’”

“Yes, she did,” Oprah says. “And we all know that note was gone.”

In the clip, Dr. Robin and Oprah also discuss Michael Jackson’s metaphorical hunger and the importance of accepting our own particular “high notes” for what they once were, without trying to top them.

Super Soul Sunday” airs on Sundays at 11 a.m. ET on OWN.
