Justin Bieber has a lot to be thankful for this holiday season.

The 17-year-old singer's grandparents, Bruce and Diane Mallette, were involved in a car accident on Tuesday, but fortunately, according to mom Pattie Mallette's Twitter page, they're going to be okay.

"My parents got into a car accident today," Pattie, 35, tweeted. "They flipped into a ditch and totaled the car, but thank God they are alive!" 

Bieber's mom explained that her dad "has broken ribs" and asked fans to "pray for him [and] for quick healing."

"Count your blessings and forgive your parents always," she added. "You never know what tomorrow holds."

Last year, Bieber gave his grandparents a 2011 Buick Encore. "They loved it and almost passed out when they saw it," he told Us Weekly of the car. "It's huge and awesome."

The pop star spent part of his holiday with his father, Jeremy, and half-siblings Jazmyn and Jaxon. "Spending time with the family -- feels really good," he tweeted. "Going to get to see these smiles on Christmas."
