The source also said that after the accident, Law's first concern was towards the well being of his children and their nanny.

"Jude's first thought was for his kids and the nanny but thankfully they were all unhurt. The only injury was his sore neck. And the car was badly damaged," the source said.

It's the second time in two months that Law has had car trouble.

Earlier in August this year, he was driving a grey Mazda in Ontario, Canada, when a vehicle plowed into the back of him. (ANI)
