Selena Gomez welcomed a new baby sister earlier this week after her mum, Mandy Teefey, gave birth in Los Angeles on Thursday.
The pop star’s mum divorced Selena’s father, Ricardo Gomez, when she was just five years old. She remarried in 2006.
Selena revealed the exciting family news on Mother’s Day.
“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,” she posted on Twitter.
She was snapped out with her pregnant mum at the Arc Light cinema in Hollywood, as the pair took time out to watch the new Great Gatsby film.
X Factor judge Demi Lovato led the celebrity congratulations on gaining a new sister, tweeting: “@selenagomez IS A BIG SISTER !!!!!! #CONGRATSELENA!!!![sic]”
Selena and her mother Mandy are thought to share a particularly strong bond as she raised the pop star as a working single mum.
“I remember my mom would run out of gas all of the time and we’d sit there and have to go through the car and get quarters and help her get gas because she never liked to ask my grandparents for money,” Selena said.
“She was really strong around me. Having me at 16 had to have been a big responsibility. My mom gave up everything for me, had three jobs, supported me sacrificed her life for me.”
