Patti LaBelle (original singer of Lady Marmalade, 1978)
'Christina sang her butt off!'
'I went to the Grammy rehearsal, rested and came back to perform with the 'Moulin Rouge' girls for the first time. I'll sleep tonight. It was AWESOMELY unbelievable! One of the highlights of my career, and I'm so happy they won!'
'I don't like to compete with others singers, I love Christina Aguilera because I think she has the most beautiful voice that I have ever heard, and I love how she dresses because she wears what she wants and she doesn't care about what people say, just like me.'
'I have always said that I'm a big fan of Christina Aguilera. She has the talent, so she can take any risks she wants... and she is Latina.'
Paul Rodgers (original singer of 'All Right Now')
For years the media said that no one would ever have the balls to touch rock's greatest anthem 'All Right Now!'
'They were right, it took a woman (Christina) and she rocked it good!'
'It's not everyday that you get to work on such a emotional song with an amazing vocal talent like Christina's, this was definitely my favorite project of 2003. I am just honored to be nominated for something I loved working on so much.'
'I think Christina can sing her butt off.'
'We butted heads a little bit, but she came to my birthday party last year, and I talked to her for a really long time. I felt empathy for the girl, and for the first time, I saw her as a human being instead of an object.'
'The kid's got talent. I think that, yes, if one wanted to be a cynic, they could say she was out to make money strictly off the bandwagon. But she's got so much versatility, power, soul and flavor, she could be singing in French and have the same appeal.'
I'd like to work with Christina, she has an amazing voice, and great song selection, I'm really into that.'
'That girl can sing!'

'Her talent has made her the favorite vocalist of today. A great chemistry developed between us and we went into the studio to experiment. The result, a great duet. Her voice is magical and really impressive.'
Responding to claims Christina is a snob: 'I think Christina is a nice girl, actually. She's been just hearing 'you're amazing, you're amazing' since her birth.'

'We spent four days on that one record because Christina is a perfectionist, and a genius of vocals'

'She looks like a cross between someone in a gay club at six in the morning and someone's who's trying to save trees.'
Shortly after his this statement he responded: 'I deeply regret slagging (criticising) her off. I hope a personal letter can mend bridges between us.'
'Well, what I love is a fun game of word association, mister, so here goes. 'Christina Aguilera?'
'Her voice is so dangerous. She does so much with it.'
Rolling Stone Magazine
'Unlike most teen poppers, Christina Aguilera can cut it without a multi tack studio.'
'There is no one else in the Latin market who can sing like her, with that whole black R&B thing from growing up in the U.S. and listening to Etta James and performers like that. By adding these new elements to Latin music, she'll take it to new places.'
'I'm going to say Christina Aguilera. She has just tremendous vocal abilities, it's amazing! Yeah, I'd love to work with her. So that's my choice of an artist.
