Kourtney Kardashian's Anointed Ms. New Booty!!!

Kourtney Kardashian's dishing up something new in Cannes, and all we can say is ... Younes Bendjima is really bringing out her best.

Kourtney threw on a pink bikini for another yacht excursion Thursday in France with her bf. He's nearby, but we figured you didn't need to see him ... not while Kourt's showing off way more ass than she usually does. Her G-string is fighting a losing battle.

Pink seems to be Kourtney's fave color the last couple days, but that fantasstic two-piece is next level.

Your move, Kim.
