Selena Gomez apparently has become a big sister. According to E! News, the "Come & Get It" singer's mother Mandy Cornett and her husband Brian Teefey have welcomed a baby daughter.

Demi Lovato sent a shout out via Twitter to Selena following the arrival of her sibling. "Selena Gomez IS A BIG SISTER!!!!!! Everyone congratulate her and her family!!!!!! #CONGRATSSELENA!!!!" she wrote excitedly on Thursday, June 13. Another Twitter post read, "RT #CONGRATSSELENAMANDYANDBRIAN !!!!!!"

Selena's parents divorced when she was five years old. Her mother Mandy married Brian in 2006. The couple expected their first child together in 2011, but she suffered miscarriage and lost the baby girl named Scarlett.

Last month, Selena shared a picture of her resting a hand on her mother's pregnant belly during Mother's Day. "Hope all the amazing moms had a great day! I have the best momma in the world :)) I love you so much!" she wrote.

The 20-year-old singer is currently working on her new masterpiece "Stars Dance". On Wednesday, June 12, Ed Sheeran was pictured leaving Selena's house with a guitar, which sparked speculation of collaboration. The "Everything Has Changed" singer wore a navy blue sweater, denim pants and black sneakers as he put his guitar case into the back of his waiting car.
