Traduko - Brazil-portugala-Franca - Você é um grande amigo ! Te adoro lindo !

Héhé, Marija, we do not say "bel" this way to someone in French. "Bel is used instead of "beau" when next noun begins by a vowel or a dumb consonant in French, such as the "h" in "homme" : "un bel homme, un bel oiseau. But with consonants we use "beau" (un beau mec, un beau petit chien)

But here we wouldn't say "je t'adore beau" either, at least would we have to add a possessive,(mon) or a noun (mâle, mec)

Or if you want to keep "bel" you still can say "mon bel ami", that would be fine as request is in meaning only.

I'll do that, (adding "ami" as a short text in meaning only must not wait too long before being validated

No, I'll add "mon beau" instead, as to avoid reading "ami" twice"...

Francky thank you for this explanation.
Now I know.
