The Fashion designer - who recently gave birth to her fourth child, a much longed-for daughter, Harper Seven - is set to send the new judge outfits from her latest collection because she knows how important it is for the former Destiny's Child singer to look her best.
A source told the Daily Star newspaper: "Victoria Beckham has offered to give Kelly dresses from her exclusive VB range to wear each week on the live shows. Victoria has a whole catalogue of new dresses and can't wait to send them over to Kelly.
"Although Victoria has just had a baby, she's always got her eye on her fashion empire and this is the perfect way to get her dresses out there. She knows how important it is for the female judges to look glamorous and up to the minute. She's more than happy to help out."
She has said: "Me and Kelly knew they'd try and make a rivalry between us from the beginning and we talked very openly about it. I'll say, 'I'm well winning the style war today, Kelly,' and we'll just laugh."
