The 'Come and Get It' singer dishes on Twitter that her little sister, named Gracie Elliot Teefey, was born June 12.
Selena Gomez has revealed the name of her newborn sister. "Momma, Brian, and me are all so grateful for all your well wishes. My lil sissy Gracie Elliot Teefey was born on June 12th. Luv you all XO," the 20-year-old singer tweeted.
