London: Teen sensation Justin Bieber`s grandparents have been involved in a serious car accident, which has left his granddad with broken ribs.
The 17-year-old singer`s granddad Bruce Dale met with the accident after the vehicle he was in with his wife Diane Dale flipped over and went into a ditch, Daily Mirror reported.
"My parents got into a car accident today. They flipped into a ditch & totalled the car but thank God they are alive! My dad has broken ribs. Plz pray 4 him 4 quick healing! Count your blessings & forgive ur parents always. U never know what tomorrow holds!!! (sic)," posted Bieber`s mother on Twitter.
The `Baby` hitmaker is thought to be very close to his grandparents after they helped raise him when his mother, Pattie, fell pregnant when she was just a teenager.
The pop star, who is in a relationship with Selena Gomez, recently said he had planned to spend Christmas with his family because they are the "most important" part of the festive period.
