The Oscar-winning actor (still feels so good to say that) is now dating model Nina Agdal, and her grandmother had something to say on the matter...

Agdal is Danish, resides in the US, and models for Victoria Secret.

Her granny Lona has revealed to the Daily Mail that Nina and Leo first met six years ago. The couple were first romantically linked in 2014 and were seen together at the Cannes film festival in May.

Last week they were spotted kissing and cuddling on a beach.

Lona’s comments that ‘now the relationship [has] apparently developed’ would now seem to confirm the pair of love birds are officially a couple.

Lona 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.’

If the warning came from an Irish mammy, to be sure it would be even fiercer than that!
