Brenda Lee (born December 11, 1944) is an American singer best known for her 1960 hit "I'm Sorry," and 1957's "Rockin' Around the Christmas Tree," a perennial US holiday standard for 50 years. She sang rockabilly, pop and country music with equal conviction and power; and as a teenager, had 46 US chart hits during the 1960s, a number surpassed only by Elvis Presley, The Beatles, and Ray Charles. She was the No. 1 female artist of the '60s. 
At 4 ft 9 inches tall, she received the nickname Little Miss Dynamite in 1957 after recording the song "Dynamite;" and was one of the earliest pop stars to have a major contemporary international following.
Lee's popularity faded in the late 1960s as her voice suffered damage and matured, but she continued a successful recording career by returning to her roots as a country singer with a string of hits through the 1970s and 80s. She is a member of the Rock and Roll, Country Music and Rockabilly halls of fame, and currently lives in Nashville, Tennessee.
