Alesha Dixon protects her modesty from a strong gust of wind as she leaves TV show

It's that time of year when the weather is so interchangeable that we're never sure what to expect when we step out of the house.

And neither did Alesha Dixon, who found herself having to protect her modesty today as she left a TV appearance.

The Britain's Got Talent judge was snapped leaving the London studios in a very pretty outfit which was made up of a black pleated skirt, chiffon black blouse and a yellow vest.

She teamed the outfit with a yellow belt and matching Christian Louboutin heels as she flashed her bright smile to the cameras.

But then the elements hit and the pop star was left battling the wind as she held her skirt down by her side in an attempt to stop it lifting up on the breeze.

Alesha was a guest on the Lorraine show this morning in her role as Avon ambassador as she launched a new campaign to help end domestic violence which also marked International Women's Day.

And she made a very quick change upon leaving the studio as she slipped into her black outfit having changed from the short, stonewashed denim dress she wore for the TV chat.

Because she was heading straight to visit the National Domestic Violence Helpline to launch Avon's Pass It On campaign and its Empowerment Bracelet to raise awareness of the global issue.

Speaking on the Lorraine show to hosts Kate Garraway and Dan Lobb, she said: 'I want people to wear and share this fantastic necklace as a symbol of women's empowerment, and infinite possibilities for women.

'It's an issue that's close to my heart. It's a serious crime. One in four women in the country are being abused and... I want to encourage more women to speak out about it.

'It's such a taboo subject. I think today's a day where we can celebrate women and encourage people to stand up and speak out, and this necklace symbolises that.'

When Alesha says it's a subject that's close to her heart, she really means it because in 2010, she made a documentary called Don't Hit My Mum in which she talked about being a child and watching her mother being assaulted by one of her partners.

She said: 'I think having a great mother and watching her be strong in herself and dealing with [her] situation [helped].

'I think if you've got somebody in your life that shows you strength and how to move forward and to break away from a situation, then that gives you strength as well.

'It's a positive thing. I think more and more women just need to be encouraged to speak out... Today is really about saying, "Look, don't be afraid anymore".'

She also spoke about being a judge on the next series of Britain's Got Talent and how much she admired fellow judge Amanda Holden.

She said: 'I love her, Amanda's one of the strongest women I've met in my life, she's amazing. She bounced back just brilliantly. She's looking amazing, she's witty, she's funny, she's really looked after me as well actually.

'And she said to me that she's a girl's girl, and so am I, and it's refreshing because you know how the media try to pit you against each other – and actually we've got on so well. And David and Simon often gang up on us, so we're sort of like the girls together, which is really nice.'
