It's like, "My beautiful girl" or "My handsome man"
It should be "ma petite belle", not "mon" ("mon" is for men in this context)."Ma petite belle" is equivalent to "my girlfriend."J'aime ma petite belle. = I love my girlfriend.
Mon belle would mean "my beautiful" if it was grammatically correct, but it isn't.belle is feminine and should take 'ma' as the pronoun.mon is masculine and should take beau as the noun/adjectiveSo, if you are speaking of a feminine thing, it would me "ma belle...." and if speaking of a masculine thing it would be "mon beau....".
Beautiful baby girl is "un beau bébé" or "une belle petite fille" in French.
ma belle it is feminine, it means my beautifu. Mon beau it is masculin it means my handsome.
bonne nuit ma belle / mon beau
Break a leg is "merde" or "je vous/te dis merde". Vous for someone with whom one is less familiar, te for a friend.

You say "my beautiful sister" in French as "ma belle soeur."

J'aime mon bel homme correction: in french you cannot call a man "belle" you use the masc. form beau. so it would be J'aime mon beau homme
