The celebrities were photographed in the kid-styled outfits by Rankin in preparation for Oxfam's Dressed By The Kids Day.
"I like to think I'm pretty stylish when it comes to my dress sense, but that went out the window on this shoot," Holden said.
"Today I look like I've stepped off the set of some mad 1980s gameshow thanks to my two girls."
Oxfam is asking the nation's mums, dads, aunts, uncles and grandparents to put their children in charge of their wardrobe in exchange for sponsorship for Dressed By The Kids Day on Tuesday 29 April 2016 - just like the celebrities below.
