Aguilera says, "I'm definitely in favour of gay rights. I think in any case your individuality is the most important thing and you have to be able to rise above anything.

"I grew up being bullied and it's not fun. It's a terrible thing and you have to try and find who your support system is and if you can surround yourself with positive people... you have to keep going. It gets better."

Cher adds, "School is the least part of your life and everyone is stupid and going though changes... it seems like it should be better now and people should be much more free, much more open and willing to accept what's going on.

"We should be going the opposite way. Bullying is a trend for everyone - I don't get that trend but it seems to me that maybe we're a less nice generation. You see it on reality shows... there are a lot of things going on that I don't get, but I've seen it."
