Busy Philipps was overcome with emotion and fought back tears as her idol, Oprah Winfrey called into the show.
Phillips has a yellow landline installed on set in case Oprah decides that she wants to call, and it seems that Oprah did indeed feel like calling Busy Tonight.
As the phone began to ring, Phillips says:
"I'm gonna start crying! I can't. I'm not ready for this."
She answered the phone to hear Oprah on the other end of the line:
"Hello! Is this you, Busy? It's Oprah."
Phillips pulled herself together and informed Oprah that she is willing to talk "anytime you want to call," even about Oprah's "harvest day."
"I'm so happy that you're on late night. It's so good to see a woman on late night!" Oprah told her.
Oprah even invited her over, and Phillips could barely contain herself. That's one thing Phillips can cross off her Christmas list.
"I adore you! Have a wonderful holiday, Oprah... And, you know, give the dogs and Stedman a kiss for me."
