New couple alert: Scott Disick steps out with his hot teenage ‘girlfriend’

He and Kourtney split three months ago – and it now seems that Scott Disick has well and truly moved on.

In fact, numerous sources say that the reality TV star and Lindsay Vrckovnik – a striking model from Canada – are now very much an item.

Despite an age-gap of some 14 years, the duo have been repeatedly spotted together in New York in recent weeks, with friends saying that Mr Disick in particular is 'bowled over' by the 18-year-old platinum blonde beauty.

And according to TMZ, on Tuesday Scott, 32, and Lindsay kicked-off a bar crawl in Manhattan. They evidently had a blast too: they stayed out until 6am on Wednesday.

Kourtney, meanwhile, was out and about for meetings in Los Angeles yesterday morning.

Looking stunning in high-waisted stripped pants and a black vest, the 36-year-old mother-of-three's demeanour certainly didn't suggest she was in anyway upset by her former partner's new romance.

Ordinarily based in Toronto, 5ft 9in, size-6 Lindsay Vrckovnik moved to New York only recently to study at the renowned Parsons School Of Design.

She just finished secondary school this summer and is believed to have met Scott while on a night out in Manhattan. 

TMZ now reports that the love-birds have headed to South Beach in Florida for some sun and sand. 

Staying at the swish Setai Hotel, the website states that Scott was 'very flirty' with his new lady friend.

"At least he's spending time with a kid… just not his own," TMZ adds.
