Lilly Margaret Brant Is Stephanie Seymour’s Daughter & a Mental Health Advocate

Lilly Margaret Brant, Stephanie Seymour's daughter, proved wise beyond her teenage years when she founded a support group for those struggling with mental health. After facing a family tragedy, Lilly Margaret Brant takes to social media to share glimpses of her life.

Eight years after the birth of her youngest son, '80s runway star Stephanie gave birth to her youngest child and only daughter, Lilly. Born into a family at the center of the modeling world— her brothers followed in their mother's footsteps and dominated fashion shows— Lilly chose to become an entrepreneur.

Although she is still a teenager, Lilly founded a support group and takes to TikTok from time to time to share moments from her life, living "life to the fullest."

Lilly Margaret Brant Launched a Support Group to Help Tackle Mental Illness

In 2021, Lilly launched an online support group for people of all ages battling mental health. Her project, Help Heal Heart, encouraged good health and well-being to those in need through support, activity participation, and advice. Her website, in part, reads:

"We want to make sure that no one is left to tackle mental health on their own."

That same year, Lilly released a list of 10 Ways to Improve Your State of Mind, where she recommended going for long walks, reading a book, listening to music, writing, and other activities to improve your state of mind.

Lilly Margaret Brant Lost a Brother at a Young Age

In January 2021, one of Lilly's older brothers, Harry, passed away after a year-long battle with drug addiction. Harry and his brother Joseph formed a famous duo with thousands of followers on their joint social media account.

Known for his good looks and his family's name, Harry attended the Met Gala by the time he was 16 and garnered a reputation as an international party boy. After his passing, his family released a statement that read:

"We will forever be saddened that his life was cut short by this devastating disease. He achieved a lot in his 24 years, but we will never get the chance to see how much more Harry could have done."

Following her brother's passing, Lilly took to Instagram and shared a throwback picture of the siblings. Harry held Lilly in his arms with his head pressed to his little sister's, and in the caption, Lilly wrote, "My amazing brother and my best friends, words cannot describe how much I will miss you."

Lilly Margaret Brant Is Currently Living Her Life to the Fullest as a Teen

Although Lilly has grown up in the public eye as the daughter of one of the first supermodels, rubbing shoulders with the likes of Naomi Campbell, and a successful father in publishing, she posts videos and pictures of herself enjoying simple moments with friends, like jumping on a trampoline.

In 2021, Lilly posted a video of her and her friends living "life to the fullest" as they shared laughs dancing under a tent. The following year, she shared a clip on TikTok of herself dawning a cowboy hat and munching on a hot dog with friends while mouthing the words to "Teenage Dirt Bag."

Despite being on the cusp of her twenties, Lilly is still her mom's little girl. In 2018, Stephanie shared a throwback picture of Lilly in her arms in honor of Mother's Day and affectionately called Lilly her "baby girl."

The year before, Stephanie celebrated her "teeny tiny" daughter's birthday with another throwback of a baby-faced Lilly cuddling a dog. In another post dedicated to Lilly, fans took to her mom's comments section and gushed about how much the mother/daughter duo looked alike.

"Like mother, like daughter...," one user commented, as another wrote," Imagine that your daughter is gorgeous. Not very surprising." A third typed to Stephanie, "She reminds me of you when you started modeling."
