The 20- year- old singer shared a picture on twitter in which she can be seen patting the baby bump of her mother, Mandy Teefey, Radar online reported.
“Hope all the amazing moms had a great day!,” the actress wrote with the picture. “I have the best momma in the world :)) I love you so much!” she further wrote.
The family had to go through a hard time last year when Teefey had a miscarriage. The ‘Spring Breakers’ star later tweeted that the name of her unborn sister would have been ‘Scarlett’.
Teefey divorced Gomez’s father Ricardo when the singer was just 5-years-old and raised her as a single mother before marrying Brian Teefey, who is said to be very close to Gomez.
