American pop star Katy Perry has spoken about how often she cries.

The 'Teenage Dream' beauty told German website Blick.ch: "I cry all the time."

She then went on to joke: "I had my tear glands removed because it kept ruining my make-up, and applying my make-up takes seven hours."

Perry then admitted: "Of course I cry. Crying is good for me."

Talking about her feelings more generally Katy Perry concluded: "I'm a very emotional person. Sometimes I'm far more emotional than I'm supposed to be. On the other hand, that's what has made me the artist that I am today."

Katy Perry's ex-husband Russell Brand has recently spoken about her in an interview with Esquire magazine. Brand described his former wife as "a lovely, beautiful person."

Katy Perry and Russell Brand got married in October 2010 in a Hindu ceremony that took place in India. By December 2011 Brand filed for divorce and cited irreconcilable differences as the cause. The couple's request for divorce was granted in February 2012 and became effective the following July.
