The 19-year-old star, who was charged with DUI, resisting arrest and driving with an expired license on January 23, posted a picture of him sitting on top of a car, reported Contactmusic.
The photo is split with a picture of Jackson, in a similar pose, standing on top of a car holding up a peace sign, taken outside a court after he had pleaded not guilty to seven counts of child molestation at a trial in 2004.
"What more can they say," Bieber captioned the picture.
Stars including Ariana Grande and Lady Gaga have leant their support to Bieber and his longtime manager, Scooter Braun, is also sticking by him.
