Kourtney Kardashian's ex-boyfriend Scott Disick was spotted in a beach at Miami with his new 18-year-old girlfriend.

Disick, who is the father of three children born to Kardashian moved on from her just a while ago and was seen with a blonde girl. Kardashian and Disick that share three lovely children were together for nine long years but never got married.

Disick was spotted with an 18-year-old model Lindsay Vrckovnik at a beach in Miami, Florida on Friday, according to ET online. They were also seen together in the New York City just a couple of days ago.

According to an eyewitness Disick and Vrckovnik were spending their holiday leisurely on a lounge chair at n the beach. The source also noted that the 32-year-old reality star was completely relaxed, smoking cigarette and drinking beer.

The duo was spotted at a bar in Manhattan's East Village on Wednesday around 10 p.m. and they were also seen attending a house party in NoHo around midnight. The pair then headed to 1 Oak nightclub where they had good time together until four in the morning.

"Scott was hanging with this girl all night," a source inside the club told ET. "He had his arm around her and they looked very couple-y. He kissed her a few times and was whispering in her ear with a smile on his face. She seemed very into him but a little out of place, very uncomfortable when people were looking at her."

The 18-year-old is with a modeling agency named Spot 6 Management based in Toronto, Ontario. The model is said to have moved to New York from Canadian City to study at Parsons School of Design.

Meanwhile Kris Jenner is happy that Disick has moved on with another girl. "At the end of the day, Kris wants Kourtney to be happy and she was sometimes very miserable with Scott during his troubled times, in what was a very difficult relationship for her daughter," a source told HollywoodLife.com.
