When Christina Aguilera gave birth to her daughter last August, “Sophia” and “Emma” topped the list of most popular American girl’s names.

But rarely one to follow a crowd, the Grammy-winning since took another tack, calling her little girl Summer Rain.

So what’s in a name?

For Aguilera, 34, a whole lot. “Summer is a time of spreading warmth and light, while rain washes away … replenishes and brings new life to allow growth and new beginnings,” she tells PEOPLE in this week’s exclusive cover story.

The Voice coach and her fiancé, film producer Matt Rutler, say the moniker captures their 6-month-old daughter’s spirit.
