Selena Gomez Will Be a Big Sister: Mom's Pregnant!

What a way to celebrate Mother's Day! Selena Gomez tweeted a picture of her and her mother, Mandy Teefey, on Sunday. In the picture, the star holds Mandy's unmistakable baby bump.

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

The child will be the second for mommy Mandy, after Selena, and the pregnancy follows an unfortunate miscarriage in 2011. Mandy and Selena's father, Ricardo Gomez, divorced when Selena was five. Mandy wed Brian Teefey in 2006. 

Congrats to Selena and the Teefey family!
