The Keeping Up With The Kardashians star was pictured with her three-year-old daughter and two-year-old niece outside a dance studio on Wednesday afternoon (14 October).
Kourtney, 36, was no doubt keeping things normal and routine for the kids despite the tragedy unfolding in Vegas.
Former NBA player Lamar, 35, was found unresponsive at a Nevada brothel on Tuesday afternoon and taken to a Las Vegas hospital. No official statement on his condition has been released but several US outlets have suggested it is critical.
His ex-wife Khloe – Kourtney's younger sister – has been at his bedside since Tuesday night, while Kim Kardashian and Kris Jenner flew out to join her.
Kourtney and sister Kendall Jenner arrived in Las Vegas yesterday, after these pictures with Penelope and North - who is Kim's daughter - were taken. It's not known if the kids are with the family in Vegas or being looked after in LA.
As well as the uncertainty surrounding Lamar, the family are reportedly dealing with Kourtney's former partner Scott Disick checking into rehab at the weekend.
It's been reported that Scott, 32, checked himself into a clinic in Malibu to seek treatment. He split from Kourtney in July after nine years together and three children, Mason, five, Penelope and ten-month-old Reign.
Sources have claimed the kids were the driving factor behind Scott seeking help.
