"Hope all the amazing moms had a great day!," Selena tweeted. "I have the best momma in the world. I love you so much!" So cute!"

The good news in the Gomez household follows the December 2011 miscarriage by Mandy, which the singer shared with her fans at the time.

Selena recently released the video for her single, "Come & Get It"; it's from her next album, which is planned for release later this summer.
