Scarlett Johansson
Before her well-publicized marriages to Ryan Reynolds and Romain Dauriac, Scarlett Johansson attended her high school prom with musician Jack Antonoff, who was also one of her high school classmates. Antonoff is known for his involvement in bands like Fun, Bleachers, and Steel Train.

At that time, Scarlett and Jack were not only prom partners but also dating high school sweethearts. They probably believed their love would last forever, though they eventually chose separate paths in life. Since then, Scarlett Johansson has established herself as one of Hollywood’s top actresses and received two Oscar nominations.
