The 39-year-old fashion designer was worried after the retired soccer star bumped their Range Rover on their driveway in October while driving their son Brooklyn, 14, and has allegedly signed him up for a crash course in safe driving, reported OK magazine.
"She was horrified about the crash because her son was in the car, so she's organised a weekend-long advanced course for him to take," a source said.
"David's not the greatest of drivers. She's threatened him with this before, but after the accident, it's a done deal," it added.
