Justin Martin doesn't really have much to sing about these days.
On Tuesday, the actor — who played Donny Dion in High School Musical 3 — pleaded guilty to five different gun charges regarding a shootout with cops last summer.
For those who might not remember, Boston police heard gunshots in the Massachusetts capital back in July, and saw the 22-year-old and another man running away while holding weapons.

Authorities chased them down and said that, while the other man actually shot back at them, Zac Efron's costar pointed his pistol at the cops, but didn't actually fire.
After the police caught up with them, Justin was booked for assault with a dangerous weapon, illegal possession of a gun and ammunition, carrying a loaded gun, and firing a gun near a building.
And on Tuesday, the HSM3 alum pleaded guilty to all charges and was sentenced to 18 months behind bars, even though the District Attorney apparently wanted to lock him up for three years.
In addition to the jail time, Justin also got slapped with one year of probation, which requires him to stay away from the crime scene, as well as drugs and alcohol.
