Nicole Richie recently shared candidly the reason why her daughter prefers to go by her middle name rather than her first name. On Wednesday, January 14th, the 44-year-old American fashion designer and actress attended an event to mark the U.S. debut of Australian makeup brand Nude by Nature, where she spoke to PEOPLE magazine about her 18-year-old daughter Harlow Winter Kate's decision to adopt her middle name.

For those who may not be aware, on Monday, January 14th, Nicole celebrated her daughter's 18th birthday by sharing a carousel of photographs that captured the moments they've enjoyed throughout the years. The Simple Life star also captioned her post with the words, "18 years of you [a heart and cake emoji] @katemaddennn."
As soon as Nicole, the mother of two, posted the series of pictures, fans quickly pointed out that the tag was under the name Kate, which is one of Harlow's middle names. Addressing people's concern about her daughter's name, she said, "Yeah, she goes by her middle name." She added, "She has her whole life," referring to the online reaction to her post.
When asked about the comments under her post, Nicole said, "I didn't look, but it makes sense... she goes by her middle name." It's worth mentioning that she shares her daughter and a son named Sparrow, 16, with American singer Joel Madden.
