Slay all day, Kourtney Kardashian!

The 38-year-old reality star is heating things up in Cannes, where she's holidaying with her new man, Younes Bendjima.

Rocking a tiny pink bikini to show off her super beach-ready body, Kardashian was spotted catching major rays on a yacht off the coast of the French Riviera on Thursday morning. 

The eldest Kardashian was accompanied not only by her 24-year-old younger man, but by her sister, Kendall Jenner -- who did some slaying of her own in a matching blue version of the same bikini.

Jenner shared a pic of the two sisters chilling on the bow of the yacht in their matching gear: "legally blonde vibes," she captioned it, adding the bikini emoji.

Kardashian's chill and sexy beach vibes make it seem like her ex-husband, Scott Disick, is far from her mind -- even though he's not actually that far.
