Lionel Richie, Eminem, and More Memorable Best Original Song Oscar Winners

While it may be a surprise to many, "Baby, It's Cold Outside" was originally written by Loesser for the 1949 film "Neptune's Daughter." The songwriter won the Academy Award for the still-popular (and often controversial) Christmas song, which was first performed by Ricardo Montalbán and Esther Williams.

Over the years, the track has been reimagined dozens of times.
