Penelope and North to goes to ballet class as Kourtney Kardashian's ex Scott Disick 'has checked into rehab'

Kourtney Kardashian was spotted in Los Angeles on Wednesday as it emerged that her ex Scott Disick has allegedly checked into rehab for drug and alcohol addiction.

The single mother-of-three's family is in a state of chaos, with Lamar Odom in a critical condition and Scott battling demons of his own, but she is keeping the show on the road for the sake of the children.

The 36-year-old took daughter Penelope, three, and niece North, two, to their usual ballet class with the help of a friend.

Both girls were dressed in tutus, with Penelope in pink and her cousin in white. 

Kourtney was taking care of North after sister Kim Kardashian flew to Las Vegas with her mother Kris Jenner to support Khloe at Lamar's hospital bedside. 

The reality star was spotted catching a private jet out of Van Nuys airport later on Wednesday, and then joined her family at the hospital.

Kendall Jenner was seen arriving shortly afterwards, having flown overnight from Shanghai, where she was attending fashion week.
