"She really can't believe that she is turning 25. She continues to joke about being too old. And every one of her friends knows she is mostly joking, but also believes she really thinks 25 is actually old.
"They have been brushing those thoughts away and keep telling her she's crazy and that she is in the prime of her life, looks amazing and that she should enjoy it to the fullest. And she is."
"She is totally looking forward to her birthday, but she sometimes can’t believe she has reached what she calls a ‘milestone birthday,'" the source said.
"Every time a birthday comes around she always looks to her mom. Her mom was so young when she had Selena and had to become an adult so early in life and Selena feels that she has so much more to prove and learn herself and she wants to become the perfect adult and person she sees her mother as, she just thought she would do it before she was 25. So that has a little to do with her thinking that 25 is supposedly an old age."
GIRL IS CRAZY, because she is definitely not old!
Hopefully whatever her boyfriend The Weeknd has planned for her will cheer her up!
