Justin Bieber has confessed that his mother gave him the prescription medication which he took before getting arrested for driving under influence.
According to law enforcement sources, the 19-year-old singer admitted of being under the influence of Rx meds, alcohol, and weed, TMZ.com reported.
When the 'Baby' hitmaker was asked what kind of Rx meds, he said anti-anxiety (such as Xanax) but wasn't much sure what kind because he claimed to be taking whatever his mom Pattie gave him.
