How to pronounce?

Catalina • Just a mom & dad expecting our third baby. We have one of each so excited to see who our tie breaker will be 💕
How would you pronounce the name "Celina"? 
Seh-lee-na 
Sell-ina
Or??? 
It's almost like the famous singer Selena and we like this spelling because if we spelled it this way then it would be just like our first daughters name with an S! (Her name is Elena)
