I love diamond facials - they leave me glowing and refreshed.

You can't help someone unless she wants to help herself. You can give her a nudge, but if she doesn't want to help herself, no one is going to be able to force her to do anything. I like that "attraction rather than promotion" approach.

I don't want to have a song like 'My Humps' and it be sagging down, so I pay attention to that area. A lot.

I have my team. Like if you see everyone around me - I have my hair and makeup girl, my assistant. They're very calm, they're all about positive energy. There're no drama queens. Everyone wants everyone else to have a positive experience. There are no agendas. I think it creates a healthy environment and there are no boundaries to cross.

A lot of times on tour it's about, 'OK, where am I today? Wow, I'm in Costa Rica. What is their famous dish?' And it's about trying the food, and really experiencing it.

Sometimes you have a noisy neighbour. You cannot do anything about that. They will always be noisy. You just have to get on with your life, put your television on and turn it up a bit louder.

My solo album is different from the Black Eyed Peas albums because I'm a singer first and foremost. There are more ballads and more intimacy between me and the listener because sometimes when you're in a group you don't have space to air out your dirty laundry.
