Taylor Swift Through the Years [PHOTOS]

Sometimes it's hard to believe Taylor Swift is only in her mid 20s! Considering her insane achievements, superstar status, critical acclaim and penchant for cat-patterned attire, it seems like she's 24 going on 400 (in a good way).

Taylor's 25th birthday -- a milestone for anyone -- is today (Dec. 13) and we figured it was the perfect time to reminisce about Taylor's career. From the cowboy boots and curly hair to stilettos and a short, sleek bob, there's no doubt Taylor's come an incredibly long way. We took a look at Taylor over the years -- from her humble beginning as a country artist, writing about love and loss, to her very public, famous heartbreaks -- and to her current status as a total pop star who has somehow managed to maintain not only her artistic integrity, but the ability to write songs that continue to be relatable and vulnerable and real.
