Scott responded to his ex’s post with one word – ‘Wow’ plus a laughing crying emoji. 

Kourtney was 27 and Scott was 23 when they first started dating in 2006.

Scott was featured in Keeping Up With The Kardashians when it debuted in 2007 and the couple’s relationship played out over the series.

The pair split for good in 2015 but have continued to amicably co-parent their kids –  Mason, 10, Penelope, eight, and Reign, five.

Earlier in the day, Scott had posted to his own Instagram, sharing a photo of his youngest child Reign.   

He was dressed in Mickey Mouse trunks and had on red, white and blue boxing gloves.

In the snap, Reign puffed his chest for the camera and let out a yell.

‘Let’s get ready to rumble,’ his dad wrote in the caption alongside the picture.
