The 38-year-old – whose children regularly appear on Keeping Up With The Kardashians – posted a photograph of herself cuddling up to two-year-old son Reign, with the reality TV babe displaying her pert behind once again in a black thong bikini.
Kourtney showed off her incredibly toned pins in the picture shared on Snapchat and she covered her brunette locks with a black baseball cap as the pair enjoyed an afternoon nap on their sun loungers.
The beauty has definitely been making the most of the glorious Cannes weather, with her holidaying alongside sister Kendall Jenner and rumoured new boyfriend Younes Bendjim.
