Selena Gomez Reveals Little Hermanita's Name. And Her Name Is...

As you all know, Selena Gomez's mom Mandy Teefey welcomed a baby girl into the world last week. Eek! We couldn't be more excited for Selena! But one thing we kept wondering was, what will they name her? We finally have the answer, thanks to Selena herself.

Selena announced via Twitter on Friday what Mami Mandy has named her new daughter, "Momma, Brian, and me are all so grateful for all your well wishes." She continued "My lil sissy Gracie Elliot Teefey was born on June 12. Luv you all XO." Gracie Elliot, how precioso is that? We love it!

Demi Lovato was the first to share through her Twitter page that Selena's baby sister had arrived.
