-(PRINCE HARRY LAUGHS) -You're in tummy.

PRINCE HARRY: This is the first time that the two of us

have ever spoken about her as a mother.

PRINCE WILLIAM: She was very informal.

-And really enjoyed laughter and the fun. -(LAUGHS)

HARRY: She was one of the naughtiest parents.

But she understood that there was a real life

outside of palace walls.

HARRY: She was our mom, she still is our mom, you know,

and of course as a son I would say that she...

She was the best mom in the world.

She smothered us with love, that's for sure.
