How to write i love you my shining star in french?

There are a few ways to translate "I love you, my shining star" into French, depending on the level of formality and the desired poetic effect:

Formal:

* Je t'aime, mon étoile brillante. (This is the most literal translation and is very formal.)

Informal:

* Je t'aime, mon étoile filante. (This uses "shooting star" which is a bit more poetic and less formal.)

* Je t'aime, ma petite étoile. (This is very affectionate and intimate.)

More poetic:

* Mon étoile, je t'aime. (This emphasizes "my star" and is more romantic.)

* Tu es mon étoile brillante, je t'aime. (This adds a bit of emphasis to the "shining star" aspect.)

Ultimately, the best translation depends on the context and your desired tone.
