Pop star Selena Gomez says she is "obsessed" with being a "big sister".
Gomez's mother gave birth to baby girl Gracie in June. Now the new addition to the family has made the 21-year-old realise the importance of being a good "role model".
"Gracie is five months old, she's adorable. I'm obsessed with her and becoming a big sister," eonline.com quoted the 21-year-old as saying.
"I know I've had the responsibility to be a role model for girls but, when you have a little sister of your own, you kinda think, 'OK, this is legit.'"
