Jail surveillance video released by the Florida State Attorney's office shows Justin Bieber and friend Khalil Amir Sharieff in custody following their arrest on January 23rd.
The 19-year-old pop star was charged with driving under the influence, resisting arrest, and driving with an expired license.
Police say they caught him drag racing on January 23rd in a rental sports car, but Bieber has pleaded not guilty to the charges.
In the video, the Canadian singer can be seen doing push ups in a prison cell during part of his 10 hours in custody.
A Florida court has set Bieber's trial date for March 3 on the charges relating to his arrest last month.
