Kourtney Kardashian apparently is not disturbed by the reports of her recently separated boyfriend and father of her three children, Scott Disick, dating a young Canadian model.

Cutting a figure of confident and content single mom, Kardashian was spotted in a sleeveless grey Pink Floyd T-shirt and cutoff denim shorts as she ran some errands in Woodland Hills on Oct. 3, Saturday, with her eldest child Mason, 5. She even cracked a smile for paparazzi while holding on to her son's hand, Daily Mail reported.

Earlier, reports emerged that Disick is seeing a 18-year-old model named Lindsay Vrckovnik with whom he reportedly  partied all night on Sept. 30, Wednesday, before heading to Miami where the pair was spotted relaxing in a pool together on Oct. 2, Friday, the Setai Hotel, before moving to the beach for a few hours.

"When Kourtney saw how old Lindsay was, she just laughed, " a source told Hollywood Life before adding that the 36-year-old TV star feels that by hanging out with such a young person, Disick has showed how insecure he is which is "a bit of a cliché for a wealthy man approaching their mid-30s."

Kardashian's present cool demeanour comes as a surprise as compared to her tear-filled breakdown over her broken relationship in the latest episode of E!'s "Keeping Up With The Kardashians," aired on Oct. 4, Sunday. The episode showed her reaction when Disick was famously photographed canoodling with his ex Chloe Bartoli in Monaco in July after which the "KUWTK" pair went separate ways.
