Selena Gomez picked the perfect time to announce that her mom is expecting.
"Hope all the amazing moms had a great day!" the Texas-born beauty, who is patting the baby bump in the pic, tweeted. "I have the best momma in the world :)) I love you so much!"
It's a heartwarming turn for the show biz family, who suffered tragedy in late 2011 when Mandy had a miscarriage; Selena later tweeted that her unborn sister's name would have been Scarlett, and the name "Scarlett Teefey" became a trending topic shortly thereafter.
Mandy divorced Selena's father Ricardo when she was just 5-years-old, and the Love You Like a Love Song singer told Glamour in November she took her mother's hard work -- in raising her as a single mom -- for granted.
"I was frustrated that my parents weren't together and never saw the light at the end of the tunnel where my mom was working hard to provide a better life for me," she said. "It's because of my mom that I can do things on my own."
Mandy married Brian Teefey in 2006, and Selena is quite close with her stepfather.
