Meet the Brains of Famous 'Frozen' Hit 'Let It Go:' Things to Know About the 'Oscar' Winning Couple [WATCH VIDEO]

Has anybody wondered how the famous "Frozen" hit "Let It Go" came to life? Meet "Oscar" winning couple Robert Lopez and Kristen Anderson-Lopez who are the brains behind the song.

In an interview with People magazine, the star couple revealed some things to know about themselves. Robert Lopez and Kristen Anderson-Lopez are two happily married couple.

"It sure is nice to be next to your best friend at those few moments when it's going well. But he's [Robert Lopez] more than a best friend - I also get to go to bed with him," Anderson-Lopez admitted.

The two songwriters won the Oscars on March 2 for Best Original Song for the movie "Frozen" with their song "Let It Go."

But prior to that, Lopez has already won an Emmy, Grammy and Tony Award. He was even considered the 12th person in history to have won all awards. Also, he was the first to have won all of them in only a decade.

But that is not yet the end of it. Lopez has also won a Critic's Choice Award, a Drama Desk Award and an Annie Award.

The down-to-earth Lopez believes that he wouldn't have done it without all the help from various people, including his wife Anderson-Lopez and his daughters 4-year-old Annie and 9-year-old Katie.

"Frozen has been a team, family effort," Anderson-Lopez told People.

"Every song we wrote, our daughters were the first audience for it and if they didn't want to hear it again, we went back to the drawing board."

"Let It Go" has been a huge success that even one man tried to sing it in 21 different Disney movies characters. Just Jared reported an impersonator named Brian Hull who posted a video on his YouTube account as he sings "Let It Go."

Hull sings the hit song using voices of Winnie the Pooh, Mickey Mouse, Goofy and many more.

"We wrote 'Let It Go' in about a day and a half. We took a walk in a park and were singing on top of picnic tables pretending to be Elsa," Anderson-Lopez shared.

Now fans of "Frozen" don't need to wait too long because on Tuesday, March 18, the Blu-ray/DVD copy of the movie is set to go on sale in stores. Fans of Frozen will also have more reason to get excited because the especially written song about the making of Frozen is included in the DVD.
