BACK TO SLIDE
Happy Birthday Selena! The American singer and actress turns 23 today, July 22, 2015. Selena's style has definitely grown and evolved this past year, so we're taking a look at her style through the years since she stepped onto her first red carpet.
Born in Texas, she was named after the famed Tejano singer, Selena, who passed just a few years after she was born. She knew from a young age that she wanted to perform, and has revealed that she was bullied as a child in school, but said "Obviously, people are going to bring you down because of your drive. But, ultimately, it makes you a stronger person to turn your cheek and go the other way."
She met and befriended Demi Lovato when they were very young, and the two are still friends today. Selena had her breakthrough role on Disney Channel, having a few small roles on shows like Hannah Montana before starring on Wizards of Waverly Place. She has since pursued music along with acting, with the band Selena Gomez & the Scene.
The singer dated Justin Beiber on and off for the last few years, bringing them both further into the spotlight. As far as her style, Selena didn't miss a beat from the beginning of her career until now: she's always been fabulous.
Okay but lets be serious, we have to ask - what do you think it's like to have the same birthday as Prince George?!
