The Entourage actress, who has modeled for Victoria's Secret, shot to fame after starring in the Carl's Jr. Super Bowl commercial in 2013.

The following year, she graced the cover of the 50th anniversary Sports Illustrated Swimsuit Issue alongside Chrissy Teigen and Lily Aldridge. 

Meanwhile, Leonardo and Nina are thought to have begun dating in June after they were spotted together in Montauk, New York.

Her dating history: Nina, who was spotted puffing away on a cigarette in the Big Apple on Tuesday, had a short-lived romance with Adam Levine in 2013 and also dated British pop star Max George

But the pair were first linked in 2014, around the time Nina and British pop star Max George split up and while The Revenant star was dating German model Toni Garrn, whom he eventually split from that December.

Nina is the latest in a long list of blonde models Leo has dated. He previously romanced Brazilian supermodel Gisele Bundchen for five years until 2005 and Israeli model Bar Refaeli for six years until 2011.

Nina, who was spotted puffing away on a cigarette in the Big Apple on Tuesday, had a short-lived romance with Maroon 5 frontman Adam Levine during an 'off' period in his on/off relationship with now-wife Behati Prinsloo in 2013.
