Celebrations are in order for Heidi Klum's youngest daughter Lou, who turned 17 on Friday.
The German supermodel, 53, shares four children, Leni, 22, Henry, 21, Johan, 19, and Lou, with her ex-husband Seal (she welcomed Leni with ex Flavio Briatore, and she was eventually adopted by the singer), and shared a gushing post in honour of her daughter's big day.
"Happy 17th birthday, my darling Lou. I love you so very much, and I am so proud of you and everything you do. Where has all the time gone?" Heidi penned, alongside a series of adorable images and videos featuring Lou.
The featured photo saw glowing new mother Heidi beaming with a tiny baby Lou in what appeared to be a photograph from the hospital.
In another snap, Heidi, who was pregnant with Lou, showed off her blossoming baby bump as she snuggled with her elder son Henry.
More photos showed a tiny Leni feeding her newborn sister and beaming for the camera as she did.
A video featured in the update showed Lou copying her famous mother, strutting her stuff for a catwalk at home.
The comments were filled with messages from Heidi's 12.6 million followers who rushed to share birthday messages with the teen.
One replied: "Incredible! You are MAGIC." A second added: "Such beautiful recordings," alongside three heart-eye emojis. Meanwhile, a fourth penned: "Sooooo sweeeeet."
All grown up
Lou's big day came just days after she appeared all grown up while stepping out alongside her famous model mother during day six of Paris Fashion Week.

Her long, curly hair was worn loose around her shoulders, while Heidi oozed her usual A-list je ne sais quoi in an all-white suit.
Heidi at home
While she only has two of her four children living at home now, Heidi has always adored having a busy household.
"I love having a house where they feel safe," she continued. "My son was barbecuing with his friends in the backyard the other day and doing all the things I taught him. It was so cute. For me, it's always the more, the merrier. I like it when they're all at home."
