Pop star Katy Perry celebrates the big 3-0 today and what a difference a year makes.

In the last 12 months alone the Roar singer has topped the charts, won multiple awards and been handpicked by the NFL to headline the 2015 Super Bowl half-time show.

It is safe to say that Perry has confirmed her status as one of the industry's most influential artists.

As the singer marks her special milestone, IBTimes UK takes a look back at the best things Chapter 29 had to offer.

She also ranked seventh on the Forbes 2013 list for Top-Earning Women in Music with earnings of $39m (£78m).

She was also crowned the Top Certified Digital Artist Ever by the Recording Industry Association of America, after gaining 72 million certified sales of digital singles in the United States, 20 million more than any other artist.
