The couple is back together after briefly splitting, reported Us magazine.
The couple was spotted together at Reagan National Airport on Saturday, January 17, in Washington, D C.
The 20-year-old actor had split with his dancer girlfriend back in August as he was busy promoting the hit drama.
"They just missed each other. He thought his schedule was too much to have a girlfriend during, he's been touring nonstop for movies and working on music, but they talked throughout. He didn't really see anyone else seriously while they were split," a source told the magazine.
