The Britain's Got Talent judges gave the thumbs down to one would-be star when he turned up on stage dressed as a Roman soldier.
She's known for her sassy dance moves and feisty pop songs but it seems BGT new girl Alesha Dixon isn't one to mince her words...
Britain's Got Talent judge Alesha Dixon launches campaign to raise awareness of the crime that affects one in four women in the UK.
Britain's Got Talent judge Alesha Dixon has described her newborn baby as "the best present in the world".
To mark her own 35th birthday, the former Strictly Come Dancing judge tweeted that she is "elated and over-the-moon" after becoming a mum.
Dixon tweeted: "It seems quick because I was hiding it for so long!!! I was in my six month of pregnancy at the Britain's Got Talent final! :) xxx"
Britain's Got Talent judge Alesha Dixon is to join forces with Paddy McGuiness to host a new celebrity entertainment series on ITV.
'Your Face Sounds Familiar' will challenge celebrities to perform as different iconic music artists every week before a panel of judges including Julian Clary and Emma Bunton. Those judged to be the best will win cash prizes for their chosen charity.
Alesha said: “This show is going to be a lot of fun. I can't wait to see their transformations and spectacular performances. I know that Paddy and I are going to have our work cut out keeping them all in line!"
Alesha Dixon and Pixie Lott have spoken about the "absolute honour" of performing at the launch of the Poppy Appeal.
The faces of the British Legion's Poppy Appeal 2012 were met with huge cheers from the crowd in Trafalgar Square.
"It is such an honour to be performing here in Trafalgar Square," Lott told the crowds before performing a series of hits including Mama Do and It's All About Tonight.
"Thank you for coming down for such a great cause as the Poppy Appeal.
"It is a privilege to be here," she added.
Britain's Got Talent judge, Dixon, said it was an "absolute honour" to perform at the launch event. She joked with the crowds as she performed a series of hits including The Boy Does Nothing and Breathe Slow.
"If it gets really rock 'n roll feel free to jump in the fountains because that always works," she quipped.
The pop divas were supported by the Military Wives Choir as the Poppy Appeal aims for a huge £42 million target after the record £40 million raised last year.
Britain's Got Talent star Alesha Dixon is already excited about returning to the panel next year, because the judges have such a laugh together.
The singer, who has joined fellow judge David Walliams in showing her support for Team GB ahead of the London 2012 Olympic Games, insists even Simon Cowell is unable to stop cracking a smile when she, Walliams and Amanda Holden are all joking around.
Dixon said: "There was a genuine chemistry. I think even Simon really, really enjoyed it, you could see that.
"As much as David was winding him up, I think he loves that. Amanda's got a filthy laugh and the two of us are constantly laughing, and I think that's the thing."
The 33-year-old former Strictly Come Dancing judge is confident all of the 2012 BGT judges will be returning to the panel next year.
She said: "Simon was really open about not wanting to change the panel. We just all genuinely get on, it's really lovely. It makes going to work really nice.
"We're not signed up yet but Simon said on the show, live on TV, that he wants the whole panel there and we've all had individual phone calls from various people to say they'd love us back.
Alesha Dixon says her friends consider her to be weird because she is happy to be single.
The judge on ITV1's Britain's Got Talent admitted she is in no rush to have children, and told Marie Claire magazine she wonders whether she may be lacking maternal feelings.
However Dixon, 33, added: "I do want kids. But I'm quite happy not having children right now. I love the fact that I can live a spontaneous lifestyle. And I love a lie-in."
