Happy birthday, Britney Spears! The stunning singer turns 39 years old today, and what better way to celebrate the star than by looking back at her transformation. Britney has been in the industry since she was just a kid, and she shot to superstardom in 1999 with her debut song and album: …Baby One More Time. At the time, Brit was just a teenager, and she proved to be the perfect combination of cute and hot, appearing innocent, but also sexy. She’s transformed quite a bit over the years, and we rounded up a bunch of photos from her time in the spotlight to show just how much things have changed between then and now.
Of course, Britney went through a bit of a rough patch in the mid-2000s, but she was able to get through it and make a massive career comeback. In 2012, she even appeared as a judge on The X-Factor. During that time, her style was much more reserved and covered-up, as she was also embracing her role as a mother.
These days, Britney is super into working out and staying fit, and she loves showing off her toned figure on social media. As she’s taking a break from the music industry, she doesn’t often attend many high-profile events at the moment, but uses her Instagram page as a way to keep in touch with her fans. Check out the gallery above to see more photos of Brit’s transformation over the years.
