The Keeping Up With The Kardashians matriarch, 59, was asked about Kourtney by ET Online while attending the premiere of horror movie The Gallows in LA on Tuesday night (7 July).
Kris simply relied: "She's good. She's hanging in there."
Reports have been circulating that Kourtney, 36, has dumped Scott, 32, after nine years together and three children: Mason, five, Penelope, two, and seven-month-old Reign.
Neither Kourtney nor Scott have confirmed this.
The speculation began when Scott was pictured looking rather close to another woman while on holiday in Monte Carlo last week. Kourtney was in LA at the time with their children celebrating Independence Day.
Kourtney stepped out for the first time yesterday since the split rumours began, joining pregnant sister Kim Kardashian to film scenes for Keeping Up With The Kardashians in LA.
She also shared a post to social media with Kim and sister Khloe, showing the girls sticking their tongues out and a caption reading: "IDFWU." That's a reference to the Big Sean song 'I Don't F**k With You'... a message to Scott?
