Robin even received a video greeting from Barack and Michelle Obama, with Michelle also announcing that she would be doing an interview with Robin in just a few days.

"I keep pinching myself, and I realize that this is real, this is actually happening," said Robin. "Faith, family and friends have brought me to this moment and I am so full of gratitude."

Before heading to the studio, she also took to Twitter with a message of hope for this next chapter of her life. "Truly is the dawn of a new day...," she tweeted.
