Taking online classes and hiring a tutor to help study in between takes on "Two Guns," Wahlberg worked in secret to get his high school diploma. The actor dropped out of school in ninth grade. He said he was motivated by his four children to finish school because he didn't want them wondering why they needed to do something he'd neglected. Fellow star Charlie Sheen also became a high school grad earlier this year.
