Nina Agdal's grandmother Lona has confirmed the model is dating Leonardo DiCaprio - but warned the Hollywood actor to "behave" or have her to answer to.
The blonde beauty's gran Lona has revealed the pair first met six years ago and admitted they are indeed a couple nowadays, but she joked the 41-year-old 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."
Nina, 24, has been busy of late and not had much time to see her grandmother, but Lona insists she is "happy" with the occasional email.
She added to Mail Online: "She is rarely home because she is very busy. I have fortunately an email from her once in a while, and I am of course happy."
The couple - who were first romantically linked in 2014 - were spotted kissing and cuddling on a beach in Malibu last week, appearing to confirm their romance, but Lona has put the speculation beyond doubt.
The 'Revenant' star and the Victoria's Secret model's friends recently insisted their relationship is "super causal".
