Louis’ biological father, Troy Austin, left his mom, and she remarried Mark Tomlinson. Together, they had Charlotte, Louis’ half-sister, who goes by the name Lottie. She is a 20-year-old makeup artist, stylist, and Instagram influencer. According to Fandom, Lottie often styled One Direction during their On The Road Again Tour in 2015, and a year later, became a Nails Inc ambassador in 2016 for a spray-on nail polish called Paint Can.
The following year, Lottie released her first book called Rainbow Roots: #MAKEUPBYME, and started Tanologist, a line of self-tanning products. When Lottie isn’t working, she loves to travel and post photos to her Instagram page, which has gained over one million followers. According to Daily Mail, the artist and entrepreneur is reportedly dating Love Island Australia star, Dan Thomas — the two were recently seen together cozying up on the beach in Barbados.
