Leonardo DiCaprio’s casual relationship with Nina Agdal

Leonardo DiCaprio’s relationship with Nina Agdal is "super casual".

The 41-year-old actor was first linked to the 24-year-old Victoria’s Secret star in 2014 and they have now rekindled their romance but friends of the model insist it is not serious.

A source told Us Weekly: "They are dating but it’s super casual."

Last month the pair were spotted in Montauk, New York where they paid a low-key visit to Goldberg’s Famous Bagels and the Montauk Point Lighthouse

In May, Leonardo and Nina were spotted partying at Up&Down nightclub in New York.

And in 2014, they were spotted leaving a club together not long after Nina’s split from singer Max George.

However, they never confirmed they were dating.

The romance is likely to come as a surprise to Essex model Roxy Horner, as it was previously claimed that she and Leonardo are "smitten" with each other.

A source said "Roxy is a really sweet, caring normal girl. She’s naturally stunning and she has a lot in common with Leo. They’re smitten and enjoy spending time together."

The actor and the model are said to have spent time together at the Coachella Festival in California in April before meeting up at the Cannes Film Festival in France last month and later reuniting in London.

Nina is Leonardo’s latest model love; the actor has previously dated Chelsey Weimar, Ela Kawalec, Kelly Rohrbach, Toni Garrn, Anne Vyalitsyna, Bar Refaeli and Gisele Bundchen.
