The Beeb's mum Pattie has cracked down on his excessive spending after he dropped a whopping $160,000 on a custom made Range Rover.
"Pattie blew a gasket when she learned about Justin's wild spending spree," a source told National Enquirer. "As a result, she is forbidding him from driving until he turns 18, unless he's accompanied by an adult chaperon."
The 17-year-old already owns a custom Cadillac 'Batmobile' and a Ferrari, so we can understand why she thought a customised "Project Kahn" Range Rover - complete with a souped-up Cosworth engine, custom paint job and a sound system worth tens of thousands of dollars - was a bit OTT.
"Pattie is trying to get Justin's wild spending under control," added the source.
Good on ya, Pattie!
