When Leonardo DiCaprio was spotted dining with newly single Miranda Kerr in Las Vegas last week, sources suggested the actor may have dumped current girlfriend Toni Garrn.

But now the Titanic star has quashed rumours of a split with a very public display of affection with stunning model Garrn, at Kanye West’s Madison Square Garden concert on Sunday night.

The Hollywood A-lister, 39, treated Victoria’s Secret model Toni Garrn to VIP tickets for Kanye’s November 24 concert, just a week after E! News reported DiCaprio enjoyed the company of Australian model Miranda Kerr at Sushisamba in the Palazzo, Las Vegas.

Initial reports from E! News suggested it was just a friendly meet-up with other pals present, but sources told this week's Star magazine that Leo has been attracted to Miranda for some time.

The publication even suggested the actor had parted ways with Garrn, however their affection display in the stands on Sunday would appear to suggest the romance is still on.

The couple were pictured kissing and cuddling during the show and even posed for an affectionate snap taken by a pal.

DiCaprio was sat just a few seats away from Kanye's fiancée, reality TV star Kim Kardashian, in a private section of the audience.

Between lavishing his lady with attention, Leo also got a nicotine fix by puffing on an e-cigarette during the gig.

Garrn, 21, a German-born fashion model, has dated DiCaprio since May and is nearly half the age of her actor boyfriend.

DiCaprio is a huge Kanye West fan, and celebrated his birthday earlier this month with a personal performance by the rapper.

Kanye, along with rapper 2 Chainz treated DiCaprio to a mini-concert at New York City's TAO.

Kim, naturally, has proven to be Kanye's biggest fan, having attended numerous nights on his Yeezus tour, including on Saturday evening, when she was joined by her mother, Kris Jenner.

Kanye’s Madison Square Garden concerts are part of a 29-date North American tour to promote the rapper’s seventh studio album, ‘Yeezus’.
