Connie Francis -- Pop Music Princess of the 1960s -- Has Died.

Connie Francis -- who dominated the pop charts in the late-1950s/early-1960s with ballads like “Who’s Sorry Now” as well as up-tempo soft-rock tunes like “Stupid Cupid,” “Lipstick on Your Collar,” and “Vacation,” died on Wednesday, according to her publicist.

Connie was 87 years old, and there is still no official word on the cause of death. However, Francis Was Hospitalized Earlier This Month For Pain-Related Problems And Had To Cancel Some Scheduled Performances.

Ms. Francis had an easy, fluid vocal style, a powerful set of lungs and a natural way with a wide variety of material from old standards, rock ‘n’ roll and country to pop songs she recorded in Italian, Yiddish, Swedish and a dozen other languages.

Along with her recording career, Francis acted as well. One of her most notable roles was in the 1960 comedy-drama motion picture "Where the Boys Are." Connie plays a dorky girl named "Angie" who heads to Florida on Spring Break with three of her college girlfriends. Although the film centers around the silliness and party atmosphere of college kids in Fort Lauderdale, the movie also deals with the subject of rape. Connie also recorded the film's theme song.

As a pop singer, Francis scored dozens of hit songs during the late-1950s/early-1960s. Of her 16 Top-10 tunes, three were chart-toppers. Here's look at all of Connie's Billboard Top-40 singles.
