Though Nicole Richie and Joel Madden's six-year-old daughter Harlow will undoubtedly raid her mother's enviable closet one day, for now, it's actually Nicole rocking her daughter's clothes.

The 33-year-old mother of two hosted the Baby2Baby Holiday Event at The Grove in Los Angeles last Wednesday, wearing a stylish furry jacket, which she later revealed actually belongs to Harlow.

"Thanks for letting me borrow your jacket Harlow," she posted on Instagram alongside this pic of her snuggling into the coat.

Though Nicole, of course, isn't the only celebrity mama raiding her kid's closet.

In July, Real Housewives of New York star Bethenny Frankel caused controversy when she posted this pic of herself on Instagram sporting her four-year-old daughter Bryn's Hello Kitty pajamas.

"This is my daughter's nightgown and PJ shorts. Think we're ready to start sharing clothes yet?" she wrote.

After she was flooded with criticism for appearing too thin and sending a bad message to her young daughter, Bethenny claimed that it was actually Bryn's idea for her to try on her clothes.

"When ur 4 year old peanut says 'mommy please put my dress on' & giggles uncontrollably, u do what ur told," she responded to one critic on Instagram.
