Nicole Richies Daughter Unveils Tattoo Tribute at 18

daughter has shared her first Instagram post since she revealed her new identity after changing her name and undergoing a dramatic transformation. 

The TV personality's daughter, 18, was born Harlow Winter Kate, but recently changed her name on social media to just her middle name, Kate.

Nicole explained afterwards that her eldest child has gone by Kate her whole life, so it 'makes sense' that she would now do so publicly.

Sharing her first post since announcing the change on her 18th birthday, Kate posted glamorous snaps with her new jet black hair and unveiled her back tattoo.

There were a pair of delicately sketched angel wings on her back, which appeared to be a nod to the pair Nicole has tattooed on her own back.

In the photos, the daughter of Nicole and her husband Joel Madden was wearing a figure-hugging gold dress with butterfly detailing, similar to her wing tattoo.

Her mother, who is best known for her appearance in The Simple Life with best friend Paris Hilton, showed her support in the comment section.

Kate captioned the pictures with an angel wing emoji, while her mother left a string of red love hearts in the comments section. 

Last month, Nicole addressed her daughter's new identity for the first time after the teen revealed her transformation on her birthday.

Nicole uploaded a sweet Instagram tribute to her daughter, by sharing a number of throwback images. But when she tagged the teen, it was revealed that she is now going by her middle name Kate.

Her dramatic transformation was also seen – with Kate ditching her honey blonde locks for a jet black color. 

'Yeah, she goes by her middle name,' Nicole told People. 'She has her whole life.' 

In regards to the reaction from social media users that noticed the name change, the star said, 'I didn't look, but it makes sense... she goes by her middle name.'

Nicole jumped to her main Instagram page earlier this week as she wished her eldest child a happy birthday. 

She uploaded a carousel of snaps to show her daughter growing over the years – with one image of the reality star holding her newborn as well as more recent pictures.
