The `California Gurls` singer - who is engaged to Russell Brand - no longer worries about other people?s opinions of her because she will always have the support of the British funnyman.

She said: "It`s weird, you know, when you fall in love and have someone that really kind of supports you, you stop really worrying about like, all this make-up you have to wear or what everybody thinks about you, because the person that you love, loves you back."

However, the 25-year-old beauty admits she still has "idiotic moments", but claims her team of assistants keep her grounded.

She said: "I have my idiotic moments too. I take it one day at a time and I have a really good support system. I have a good team. I don`t end up wasted, with my face down in alleyways. I kind of like, steer the ship pretty good so that I don?t hit any icebergs."

Discussing her new single `California Gurls`, Katy claims she wanted to make an anthem for the US state to rival Alicia Keys` song `Empire State of Mind`, which is about New York.

She explained to US TV show `Access Hollywood`: "I heard `Empire State of Mind` and I love that song. There`s been, you know, `California Love` and there`s been `California Girls` by the Beach Boys, which is probably one of my favourites and I just thought, how perfect to kind of take that idea and give it my spin."
