Katy Perry: I'm a bridechilla

Katy Perry is a "bridechilla".

The 35-year-old singer is set to marry movie star Orlando Bloom, and Katy has insisted she's adopted a relaxed approach to their upcoming wedding.

Katy - who was married to comedian Russell Brand from 2010 until 2012 - shared: "I call myself a 'bridechilla' as opposed to a bridezilla. Orlando and I are united with our approach.

"It's not about the party, it's about the coming together of people who will hold us accountable when things get really hard. Because it's really great and then it's really hard.

"Those are just the facts when you're with someone who challenges you to be your best self."

Katy is one of the world's best-selling pop stars, and she's conscious of her role-model status.

The chart-topping star thinks she has a "good moral compass" because of her parents.

She told Stellar Magazine: "Young people are so influential, I'm so influential and every interaction results in a feeling - and it really is how you use those feelings.

"I have boundaries with adults, but when I'm out and kids want to come up and say hi, I will never say no. I'm conscious I might only meet them one time and it might have a huge effect on them."

Despite this, Katy is aware that she occasionally has bad days.

And the pop admits that Orlando, 43, has seen the "best and the worst" of her personality.

She said: "I do try and live in a really kind, integrous way. And I'm not always that way - I have bad days as well, you know?

"Sometimes my fiance would say, 'OK ... maybe not today.' It's funny how your partner gets both the best and the worst of you."
