TMZ obtained the snaps of Bieber holding an alleged blunt and laughing with friends, including 19-year-old Lil Twist, who was driving Bieber's car at the time the paparazzo was killed on a highway in Los Angeles, Calif., on Jan. 1. According to sources at the party, Lil Twist and his brother were the ones dishing out the pot to guests.
After the photos surfaced, Bieber took to his Twitter to issue an apology of sorts.
"Everyday growing and learning. trying to be better. u get knocked down, u get up," he wrote last night. "Back on tour tomorrow. ready to see u all smile. time to do what im supposed to be doing. performing. #BELIEVEtour."
