It seems like you are trying to express something in Spanish, but the phrase is in French.
To help you translate it correctly, please tell me:
* What are you trying to say in Spanish?
* What is the context of the phrase?
For example, are you trying to say:
* "Well, I want to tell you something, you are beautiful."
* "Well, I want to tell you something, you said beautiful."
* "Well, I want to tell you something, you call her beautiful."
Once you give me more context, I can provide a more accurate and natural translation in Spanish.
