Dr. Phil and Oprah Winfrey have been close friends and professional colleagues since she first invited him to be a regular contributor on The Oprah Winfrey Show over 23 years ago.

On the latest episode of Dr. Phil’s new podcast, Phil in the Blanks., dropping this Tuesday, Dr. Phil says that he’s never forgotten the help Oprah gave him. He also reveals that he sends her a message - at least twice a year – “Just for the purpose of telling you how much I appreciate how much you’ve done for me and my family.”

“I think the most you can offer someone is your sincere gratitude for them being in your life,” she responds in the video above.

Hear more from Oprah, and learn all about her new book: The Path Made Clear: Discovering Your Life's Direction and Purpose, on this week’s Phil in the Blanks.
