It seems like little Maxwell has recovered nicely from her impromptu haircut earlier this month. Simpson, 36, revealed her eldest child accidentally snipped off one of her own locks when she got her hands on a pair of scissors.

The fashion entrepreneur and mother of two posted a photo of the piece of hair in a plastic bag labeled with the event's date to Instagram, captioning it with the hashtag "#MommyIsNotHappy."
