"There enthusiasm kept me Going!!!

"They were also going to school and rehearsing every night. !! . am so very proud of all of them. I think what my children learned the most this year of rehearsing and performing is that if you who to follow your dreams, you have to work hard for them."

"And if all of them choose something different later in life, they will never forget this year of blood, sweat, and tears. Nor will I. It's a CELEBRATION. (sic)"

In a recent interview, the 'Frozen' hitmaker gushed about "making magic" with her "family of artists".

She told W magazine: "When I go on tour, nothing brings me more happiness than to know we are all working on the same show, creating the magic together.

"It would be boring if they were just travelling from hotel to hotel, and occasionally coming to watch the show.

"Of course, I am their mother so sometimes we get on each other's nerves. We are a family of artists but we are also a family, and that's what happens."
