The 41-year-old actor and his 24-year-old model girlfriend were involved in a minor fender bender on Saturday (20.08.16) when a car crashed into the back of theirs.

However, PEOPLE reports that everyone involved escaped uninjured and are "all are doing great".

The New York Post's Page Six first reported details of the accident and revealed they were in Leonardo's friend's car at the time.

An ambulance was called as a precaution and Leonardo checked to make sure everyone was fine.

Meanwhile, after some speculation, Nina's grandmother confirmed the model is dating Leonardo last month, and warned him to "behave".

The blonde beauty's gran Lona revealed the pair first met six years ago and admitted they are indeed a couple, but joked the actor would have her to deal with if he upsets her granddaughter.

She said: "We have not said hello to him [Leonardo] but we hope that he behaves towards her. Otherwise he will get me to deal with.

"I can tell you that it is six years since they first met, and now the relationship apparently developed."
