The 19-year-old arrested with pop star Justin Bieber in Florida Thursday morning is a Sacramento rapper named Khalil Sharieff.
Bieber and Sharieff were arrested in Miami Beach, Florida Thursday and are accused of racing and driving under the influence.
Both appeared in court by early afternoon to hear the charges against them.
Sharieff tweeted a picture of Bieber last night in the yellow Lamborghini he was pulled over in.
Sharieff is originally from Sacramento, he grew up in Antelope and was signed to Def Jam Recordings when he was just 15.
It is unclear whether he is currently with another recording label.
