Miley Cyrus says her dad, Billy Ray Cyrus, caused her to suffer a "head injury" when she was just two years old.
The 'Midnight Sky' hitmaker has confessed her famous father took her out on a dirt bike when she was just a toddler, and the trip resulted in a nasty injury which Miley has been monitoring for years by getting regular brain scans.
And the 27-year-old singer thinks her injury may have impacted her brain's development, as she says there are qualities about her personality that don't always make sense to her.
