Neil Patrick Harris better know how to Let It Go. Kristen Anderson-Lopez and Robert Lopez, the Oscar-winning husband and wife team behind Disney’s Frozen, will pen an original musical number for the awards show host to perform on the Dolby Theatre stage on February 22nd. The couple said in a statement: “We love the Oscars and have always been huge Neil Patrick Harris fans, so when he asked us to write him a song for this year’s show we said, ‘Yes!’ before he could finish the sentence — it’s possible he may have been asking us for something else. We are having so much fun collaborating and have even enjoyed weaving our experience as Oscar nominees into the song.”
