'Katy Perry'
'Katy Perry'Wikipedia

Katy Perry is one of the most successful singers and songwriters of recent times. Though her songs are considered attention grabbing with controversial lyrics by many, she has numerous accolades in her name including three Guinness World Records.

Perry initially used to sing in church in her childhood and pursued a career in gospel music as a teenager.

After her debut studio album "Katy Hudson" released in 2001 didn't do well, she moved to Los Angeles to try her luck with secular music after her former studio, Red Hill, closed down.

However, success didn't come before 2008 when she released the singles "I Kissed a Girl" and "Hot n Cold." Her third album, "Teenage Dream" (2010), included the U.S. Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream," "Firework," "E.T.," and "Last Friday Night (T.G.I.F.)."

As the singer-actress celebrates her 31st birthday today, here is a list of five less known facts about her that may leave you flabbergasted!

1. Katy Perry is her stage name

Katy Perry's real name is Katheryn Elizabeth Hudson. When she rose to fame in 2008, she changed it to Katy Perry to avoid being confused with the actress named Kate Hudson.

2. She belongs to a religious family

Though Perry's songs are often rebellious and emphasise controversial and sensitive subjects, her parents were very religious people and considered the derogatory topics blasphemy. They were rigid in their belief system so much that Perry and her two siblings were not even allowed to read "Harry Potter" or watch "The Smurfs."

3. She has a collection of other celebs' hair

Cinema Blend reported that Katy Perry loves to collect the hair of other celebrities that she keeps in her collection.

"One of the first times I went to the Grammys, I got to share a dressing room with Miley Cyrus and Taylor Swift. And I asked for a lock of their hair from each one of them, which is totally creepy, but awesome," she said.

4. Perry and Michael Jackson

What's common between Perry and MJ? The fact that she is the only artist in the history of American music since Michael Jackson who has 5 number 1 hits from the same album, as reported by Billboard.

5. Katy Perry never had plastic surgery

Katy Perry has amazingly good looks, there is no doubt about that. Rumours have been around for a long time that she went under the knife for that perfect skin and a great body.

However, Perry has denied all such allegations and said that her good looks are simply the result of a good diet, regular exercise and a healthy lifestyle. She also said that she has never gone under the knife and won't do it ever.
