This is Robert Lopez, the 39-year-old songwriter behind Frozen's massive hit "Let It Go."

On Sunday, he won an Oscar for Best Original Song with his wife, Kristen Anderson-Lopez, which makes him a new member of the elite EGOT club, meaning he's won an Emmy, Grammy, Oscar, and Tony.

To date, he's won three Tony Awards — for Best Original Score (for Avenue Q) in 2004, for Best Book of a Musical (for The Book of Mormon) in 2011, and for Best Original Score (for The Book of Mormon) in 2011 as well — two Daytime Emmy Award for Outstanding Achievement in Music Direction and Composition (for The Wonder Pets) in 2008 and 2010, and a Grammy Award for Best Musical Theater Album (for The Book of Mormon) in 2012.
Here are the Lopezes with their daughters, whom they thanked during their acceptance speech (which they partially sang).



And in the press room after their win, this happened:
Robert Lopez's wife just gave him an ADORABLE homemade EGOT necklace made by her & their kids. Can't take a photo! I'm sorry! #LetItGoOscars
