It’s been all good news for Selena Gomez recently, as the Spring Breakers star, who also recently released the highly successful Come and Get It single, has become a big sister. On Thursday, Selena’s mother, Mandy Cornett gave birth to a baby girl with husband Brian Teefey. Gomez had announced the pregnancy to her Twitter followers a month prior, saying: "Momma and Brian are finally letting me share the news...My mommy's carrying my baby brother or sister :) I'm the happiest girl in the world!"

Now, 20-year-old Selena is presumably too wrapped up in doting on her baby sister to take care of her social media duties. However, New York Daily News reports that pal and X Factor judge Demi Lovato took to Twitter immediately after hearing the news to congratulate her friend. "@selenagomez IS A BIG SISTER!!!!!! Everyone congratulate her and her family!!!!!! #CONGRATSSELENA!!!!" she tweeted Thursday, adding "#CONGRATSSELENAMANDYANDBRIAN !!!!!!"

This is the star’s first sibling. Selena’s parents separated back when the future Disney girl was just five years old, but the family has obviously made it work. Now, Gomez will have to balance family responsibilities with her career, which is on a definite rise this year. She has steadily been trying to distance herself from her Disney past. After releasing Spring Breakers, in which she plays one of four girls on a vacation that gets out of control, Selena dropped the first single off her new album and an accompanying video, showing off her sexy side. Now the actress is looking forward to future career prospects and, if recent news about her are correct, she is even prepared to do nudity for a worthwhile role.
