The Keeping Up With The Kardashians star shared a snap to Instagram on Monday (16 February) showing her little man's very stylishly-clad legs and feet.
Her caption simply read: "Baby vibes."
Oh, Kourtney, you tease!
While the reality star's other two children – Mason, five, and two-year-old Penelope – have been featured in the family reality shows and frequently photographed, she's been keeping little Reign hidden from the public.
Kourtney and long-time boyfriend Scott Disick welcomed Reign, their third child, on 14 December 2014 – the same day as son Mason's fifth birthday!
As well as keeping Reign hidden from view, Kourtney has largely been keeping herself away from the cameras – unlike her famous family who have been all over the place at New York Fashion Week!
Meanwhile, in other Kourtney news, she spent yesterday afternoon at the cinema with Scott watching movie of the moment, Fifty Shades of Grey.
"I know I'm not the only one who thinks Christian Grey is a perfect gentleman," she wrote. "#50shades #datenight."
