Justin Bieber's grandparents Bruce and Diane got into a car accident. The car actually flipped over in the snow and was completely totalled.

The accident was caused by slushy snow, which can be really dangerous.

Justin's mom Patti tweeted "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!!!"

Luckily, everyone is back at home and safe. Let's hope they feel better soon!
