Justin Bieber's former sidekick, Lil Twist, has been sentenced to a year behind bars after pleading no contest to beating and robbing a Nickelodeon actor. The news may come as a shock to Bieber who hasn't been seen with his pal recently but was once rarely spotted without him.

Los Angeles County district attorney spokesman Ricardo Santiago tells The New York Daily News that the 23-year-old rapper, whose real name is Christopher Lynn Moore, entered the plea on the first day of his scheduled trial Wednesday. Santiago says the plea wasn't negotiated with prosecutors, who objected to it.

Prosecutors said the charges stemmed from an occasion two years ago when "Zoey 101" star Christopher Massey asked Moore to leave a party. They say Moore returned to the party with others and beat the actor.

Moore tweeted after leaving court Wednesday: "It's over but not really, GOD got me!!"

Lil Twist was once part of Bieber's close entourage of pals. He appeared to living with the pop star at one point. In 2015, the friends released a song together, but they haven't been spotted together in recent months.

Moore's sentence comes as Bieber has been embroiled in his own headline-making behavior. He has recently faced backlash for reprimanding screaming fans at his shows. Last week, he seemingly punched a fan and made him bleed.

The pop superstar hasn't publicly commented on Moore's sentence.
