Her older brothers Max and Harvey Mills already had substantial audiences as entertainers, giving Tilly an early connection to the digital entertainment world.
She became particularly prominent on TikTok. Her videos included lip-sync performances, dance clips, singing videos, family content, and collaborations featuring her brothers and friends.
Some of her most recognizable content involved popular music and viral sounds. She posted videos singing along to Olivia Rodrigo‘s “good 4 u” and used a Jason Coffee sound associated with the phrase “We are going to Disneyland.”
Her ability to combine singing, dance, humour, and family appearances helped establish her as a young digital creator. Tilly Mills created a YouTube channel called Tilly Frills on June 1, 2017.
Her videos included challenges, family appearances, slime-related content, singing, and other entertainment aimed at a young online audience. One early upload was “Mega Sour Sweets Challenge!!”, while another featured her brothers in a slime-making video.
Her performing background extends beyond social media. She has trained in ballet, tap dance, and guitar, and her online videos have let her showcase vocals and dance. She has also appeared at youth entertainment events, including Slimefest at Blackpool Pleasure Beach and the 2018 premiere of Knight Squad.
A major evolution came in May 2024, when she collaborated with her brothers to launch the 13 Again Podcast. The talk-centric audio project focused on youth lifestyle topics, serving as a dedicated medium to elevate her growing individual digital profile.
After her birthday milestone in March 2025, the production formally rebranded as the 14 Again Podcast and gained over 135,000 YouTube subscribers.
As she entered her teenage years, Tilly Mills‘ public presence became more limited, particularly after her former TikTok account disappeared. Her Instagram presence has continued to provide a platform for selected family and personal content.
