Justin Bieber claimed that he had an injured foot after undertaking a wobbly sobriety test in a police station earlier this year.

The singer was pulled up cops in January in Miami and was arrested on suspicion of DUI, driving without a valid licence and resisting arrest.

Video footage later emerged of Bieber undertaking a sobriety test in a police station as the forces processed his arrest.

However, a new police report issued on Tuesday (March 18) says that Bieber complained after doing the test of having an injured foot sustained via skateboarding. Police noted that the injury was never mentioned after the test.

Speaking meanwhile to cops about why he was out in Miami driving a Lamborghini, Bieber said:

"I'm 19 years old. I'm just out having a good time. What were you doing when you were 19?"

When the police officer replied saying that he wasn't driving Lamborghinis around, the now 20-year-old said:

"Yeah, well, I bet you didn't have millions of dollars in your bank account either."
