Ok, it was not a great performance but I think she's even more courageous to go back in stage after all that she's been through...
Britney is a warrior and I think that she's here for a long time.

Ouassan, paris, France

She shouldn't really of lipsynched on a live show where the contestants were singing her songs, but hey last time she performed she bombed big style so imagine what state she was in before that curtain lifted. If you listen to her new album she is back to her former glory! You go girl!

Sarah, Leicester,

I thought she was terrible on X Factor. The song was awful, her dance routine was abysmal and as Oscar Wilde would have said, she was, "Vulgar, vulgar, vulgar"!

Philip, Rhondda, UK

She danced like a heavy amateur who has never seen a stage. She didn't sing. She answered the questions as if there wasn't a single brain cell in that head.

As a performer and celebrity, it was appalling and embarrassing to watch. As a human, it's very sad. She doesn't need to do this any more.

Laura Roberts, London, UK

and lets not forget, this is her first time back on stage in a long time. Shes just getting back the feel of the audience and trying to get over her nervousness. She will get better and better with more practice. I thought she did great!

Sascha, New Castle, PA, United States

One day this young person will get her confidence back & realise she has enough talent & looks to put us all to shame, she's obviously been through, and is going through, a lot, like most of us probably have, but not for all to view. She has stunning voice, I look forward to that day.

Daniela, Vienna, Austria

Right. Did you even SEE her performance? It was full of energy and the people at the performance were going crazy with all their screaming! Since when does such a reaction mean they don't like what they hear?

GewundadFeorh, Adelaide,

James Brown did it. Prince does it. Tina Turner, Bruce Springsteen and even Christina Aguilera all have extremely energetic stage shows and yet still have the artistic integrity NOT to lip-sync. What do they all have in common? Soul, talent and integrity. Wake up and smell the plastic.

Brett, ny, usa

She neither danced nor sang. Instead she just walked aounrd stage with a track playing over the top.

The crowning moment was the sight of the MC handing a hand-held microphone to someone kitted with a neck mic.. . . Since when did a neck mic become a piece of jewellery?

I think britney spears x factor performance was a massive embarassment , she was worse than the x factor rejects. SHE can't sing which is a real problem on a live singing show & her dancing was so bad I was stuned, I do hope simon cowell didn't pay to much for her if he did he was robbed.

mrs r everitt, woodford, england

Britney never sings live, you try doing all that dancing and singing. It's physically impossible. Too much breathing.

Scott, Scotland,

Her dancing was minimal, and her mime was even worse.

raymond david bookbinder, altrincham, england

Wasn't one of the X-Factor judges, now artistic director or something, a choreographer for Britney Spears, and bemoaned the lack of UK talent? Just shows what he knows!

David Leslie, Perth, Scotland

Maybe she had realised that the contestants would totally outshine her in the live singing so concentrated on the dancing instead.....

Julie, Swindon,

If people like same difference can mime on the X Factor, i think there is no question to Britney spears being allowed too also.... she looked fab and i am just glad to have her back on top, give her some slack!!!

Erin Doyle, Northern Ireland,

what a stupid article, stop picking hole sin everything she does, she is an entertainer, and on saturday she entertained! I bet anything there where more people who enjoyed it than didnt, but everyone has to focus on the negative! it was an entertaining performance!!

JOE, EASTBOURNE, UK

Let's face it, Britney's had her day really.

Sue, Banbury,

WOMANIZER isnt really a song u can sing live to, its an electro dance song, with vocal alterations, its not meant to be a song u can sing live! she done fine just leave her to it!

Tom, Polegate,

After all she's been through I expected to see a less fabricated star with a little bit of personality. Instead what I saw was an empty, boring, sad and innocuous performance. She's not having a penny from me Big Time!!!!

Ricardo, Brighton, UK

This show is long past its sell-by date The contestants can't sing - tRuth wasn't quite as bad as the one who screeched throughour but they're all pathetic. Who decided to invite B Spears I can't imagine; what a role-model to hold up to a mass audience, some of whom are young,. Scrap "The X Factor"

Jan Thomas, Niottingham, England

It was so bad it was good! I love Britney!!

RJ, London,

Dreadful performance by Britney Spears on X Factor! She always mimes. On a show like X Factor when its all about live singing. It was diabolical Miley Cyrus who is 16 years old sang live and was excellent. As for the judges standing up for Britney. Shame on you!

Mandy Lewis, Portsmouth, Hants

Just goes to show how good the X-Factor contestans are. They can sing and dance at the same time. Standing ovations are probably a contractual obligation - like the one for Mariah Carey's miming. Seems like all X-Factor guests mime, even previous show winners.

Ron, Milton Keynes, UK

i love britney!!!!!!!!

chris, doncaster, ENGLAND

Was going to buy my daughters some tickets for Britneys O2 concerts next year as a Christmas present, but after that performance, I'll save my money. Ruth Lorenzo would be worth paying to see. What a great singer and charming lady.

Joe, Belfast,

enough said...

Bryan, Ramsgate, UK

She just waddled around to music - any one of the contestants that night was far more entertaining and talented!

Gabrielle, London,

REM also objected to being asked to mime on TOTP - eventually they performed Orange Crush with Michael Stipe hiding his face behind a bull horn. He has since used this prop on other occasions when performing this song and actually singing.

Austin, London,

Well I think it was a travesty. Especially on a talent show where all the contestants are supposed to "see how it should be done". As for miming to allow her to concentrate on the dancing... strutting around a stage with your backside hanging out hardly constitutes dancing! Britons expect better.

Margaret Hastings, Sheffield, England

Was v disapointed she did not sing live...expected her 2 has she was on x factor.. did not think much 2 the hole thing.
