Whos the oraginal singer of "baby its cold outside"...?

In 1948, after years of informally performing the song at various parties, Loesser sold its rights to MGM, which inserted the song into its 1949 motion picture, Neptune's Daughter. The film featured two performances of the song: one by Ricardo Montalb谩n and Esther Williams and the other by Red Skelton and Betty Garrett. These performances earned Loesser an Academy Award for Best Original Song.

The original composer was Frank Loesser
