Relationships are about helping motivate each other to be all that you can be.

I realised that we're all equal - it's all about helping each other.

Before 'American Idol' and all this stuff, I was obsessed with music charts, and I used to go online to find out what was popular in other countries. I'd log on to the BBC website, and that's how I found out about artists like Natasha Bedingfield, Daniel Bedingfield and Take That.

That's the most gratifying thing in the world, helping each other.

One pretty amazing thing we learned early on was that the more time we spent together, the better our relationship was.

I guess other people's compliments motivate you.
