Selena Gomez still feels 15

The 'Come and Get It' hitmaker, who has an on-off relationship with Justin Bieber, is gearing up to celebrate her 21st birthday on July 22, reported Contactmusic. "I feel like sometimes I am 15 in my heart. You know, sometimes I just go in waves of being a child and being an adult.

It's awkward, I am growing up. I am just trying to figure out who I am," Gomez said. But the 'Spring Breakers' actress is looking forward to celebrating the milestone in Los Angeles next month and being legally able to drink alcohol. "I'm going to enjoy being 21, absolutely, of course. I am going to have a party... My family from Texas, my friends and my cousins are flying in. I will have some of my best friends in LA," she added.u00a0
