ET has the latest...

Larry King has interviewed the biggest names in modern history, but rarely does he allow the cameras to be turned on him.

I have had the privilege of being one of the few journalists to be granted access to Larry and Shawn King's glamorous world on numerous occasions. But it still came as an honor to be invited into the King home this week. The Kings wanted to speak openly about Shawn King's reliance and subsequent freedom from migraine medication. Their hope: Shawn's story would inspire others who are suffering in silence.

The room was packed with dozens of handlers and CNN network staff. At the center of the nervous frenzy sat the Kings, side by side. Shawn looked radiant, relaxed and ready to reveal one of the deepest secrets in her heart.

The statuesque blonde beauty spoke candidly and eloquently of her reliance on migraine medication, telling our cameras she has suffered from mind-numbing migraines since she was a child. Over the years, she built up a tolerance to the meds, which she felt was both unhealthy and could lead to a dangerous addiction.

Thankful for her many blessings including a burgeoning career (she's starring in a new movie, recorded with Willie Nelson and was hand-picked by Danny Gans to open for him in Las Vegas next year), the entertainer did not want anything to hold her back.

She says, "I went through a little bit of a bumpy patch there. But, I came out the other end great."

Today, the King's marriage is more rock solid than ever.

King says of his wife, "I am in her shadow."

Meanwhile, both Larry and Shawn are involved in the Lundon's Bridge School Fundraising Franchise, which will release five books and five movies with half of all sales going to American schools. The movies will be released and shown exclusively in school theaters.

Shawn portrays Queen Dalina, a jellyfish who rules the seven seas, while Larry portrays King Pom, the king jellyfish who rules the seven seas alongside his queen!
