Catherine Zeta-Jones
As a child, Catherine Zeta-Jones had to have her windpipe repaired, leaving her with a one-and-a-half-inch scar at the base of her throat. “Make-up artists are still attempting to cover it up, but I don’t want to conceal it,” she told People in 1998. “If I didn’t have this scar, I wouldn’t be here today.”
Jonah Hill
In a 2010 Rolling Stone interview, Jonah Hill admitted that after his mother was diagnosed with cancer, he became a “bad boy.” So when the teen crashed an SUV and smashed his thumb, everything came to a head – and the star cleaned up his act after the wake-up call. “I look at this scar every day,” he told the publication. “It serves as a reminder to me to work hard.”
