Relationships:
In late October 2010, Katy tied the knot with fiancé Russell Brand in a traditional weeklong Hindu ceremony in India after a whirlwind courtship.

Katy was previously romantically tied to Gym Class Heroes frontman Travis McCoy, who now goes by the name Travie for his solo endeavours – reportedly the negative inspiration behind her song Circle the Drain.

Before They Were Famous:
Katy grew up in a devout Christian household and was involved in the religious community from a young age. Her pastor parents encouraged her to sing gospel and hymns, and she recorded a Christian gospel album under her birth name Katy Hudson in 2001. Many years and several failed albums later, Katy finally took the international music world by storm with instant hit I Kissed a Girl in 2008.

Career Highlights:
Sporting a new name and adopting a new, funky yet controversial style, Katy Perry is one starlet who has earnt her fame. Her first mainstream album, One of the Boys, includes the worldwide hits I Kissed a Girl, Hot n Cold, and Waking Up in Vegas. Her 2010 album, Teenage Dream, has also been a phenomenal success, with the title track, California Gurls and Firework all reaching the top of the charts.

After launching her first fragrance in November 2010, called Purr, the pop star is set to make her big screen debut in 2011, voicing Smurfette in The Smurfs alongside Neil Patrick Harris.
