Preklad - Anglicky-Italsky - Happy 28th Birthday Reneè!

The context of this translation is so that I could put it on a banner for my fiancé. When I try translating in Google, it puts a symbol similar to the empirical degree symbol after the number 28 and I am not sure this is correct. I would like to see what this translation looks like with the '28th' as a number and written out.

The symbol in Google translation means that, but in Italian you can use 'esimo' after the number to give it the 'th' meaning
