Paris Hilton poses with childhood photo for Hugo Boss ad

And Paris Hilton engaged in some nostalgia following the major life change on Thursday when she shared a photo of herself posing with an adorable picture taken when she was just a child. 

The 41-year-old socialite was joined by models and stars including Gigi Hadid, Naomi Campbell and Demi Lovato as they all shared pictures of themselves as children for a new Hugo Boss summer campaign.

The fashion house unveiled the new campaign on social media on Thursday, while sharing several of the striking portraits to its own social media accounts.

Paris opted to represent the the fashion house in her photo via a navy blue hoodie that she wore which featured ‘BOSS’ in block letters on her chest that were enlivened with brown, white and black stripes.

The blond beauty also wore a set of black fingerless gloves — a style she has repeatedly returned to — as she held a black-and-white photo of herself in a dress with a lacy white satin collar.

The adorable child version of her showed off a sweet mile and had a lace-covered flower placed in her hair.

The House Of Wax actress complemented her old photo by wearing her long hair in thick curls cascading down her shoulders.
