Lady Gaga, Ryan Reynolds, Scarlett Johansson's yearbook photos published

(CBS/AP) LOS ANGELES - Before fame and fortune came calling, stars still posed for photos. But those pictures ended up in yearbooks, not magazines.

Ancestry.com has expanded their U.S. School Yearbook Collection, and it includes snapshots of Lady Gaga, Ryan Reynolds, Scarlett Johansson, Bradley Cooper and others.

The images include Cooper's teenage tennis practice, Gaga's first communion, a young Johansson decorating a Christmas tree, Reynolds goofing around with his high-school classmates, and singer Blake Shelton as a guitar-playing kid.

The genealogy website recently expanded its yearbook database to include nearly 7 million images from thousands of schools in the United States. The database is designed to provide insight into family members' school years, says Ancestry.com executive vice president Josh Hanna, "and while you're searching, you might just find a famous classmate."

Other the celebrities included in the expanded database are Jon Stewart, LeBron James, Justin Timberlake, Gwyneth Paltrow, George Clooney, Will Ferrell and Sean Penn, sporting shaggy locks like his Jeff Spicoli character from 1982's "Fast Times at Ridgemont High."

The expanded U.S. Yearbook Collection will be available beginning Aug. 24.
