Selena Gómez Mom Pregnant: Mandy Teefey Expecting Baby Girl

Last Mother's Day was extra special for Selena Gómez and her family: the singer revealed that she will be a big sister!

Selena tweeted a photo of her and her mom, Mandy Teefey, who is sporting a sweet baby bump. The singer and her mother look relaxed and happy.

"Hope all the amazing moms had a great day! I have the best momma in the world. I love you so much!" she wrote.

It will be the second child for Teefey, who divorced Selena's father whe she was just a toddler, and went on to wed Brian Teefey in 2006.

Teefey suffered a miscarriage in late 2011, from which she took a couple of years to recover.
