The Tomlinson family is still devastated by the loss of their sister, 18-year-old sister, Félicité Tomlinson. Lottie Tomlinson, another sister of former One Direction singer Louis Tomlinson, took to Instagram on March 19 to share her heartbreak with fans.

“My Fizzy, my baby sister, my best friend,” she began, five days after the shocking death on March 14. “I’m incomplete without you, I’m empty. I can’t picture my life without you. I wish we could have lived life together for a little longer.” The pictures show just how close the 20-year-old was with her younger sis — they can be seen posing for photos as kids and hugging as adults. It’s crystal clear just how special Félicité was to Lottie.

However, the influencer tried to find the silver lining in the devastating situation. “Mama needed you and you needed her, you’re finally together again,” she said. “I love you always, Dotty x.” Of course, the Tomlinson family also lost their matriarch, mom Johannah Deakin, in 2016 following a battle with Leukemia.

Louis and Lottie’s 15-year-old twin sisters, Daisy and Pheobe, shared the same sentiment. “Mummy needed you and you desperately needed her,” wrote Pheobe in her own Instagram post. “I’m so glad [you’re] together now and she has you to rub her feet in heaven like you used to. I pray that you’re in a better place now. We love you like you wouldn’t believe. Fly high my beautiful sister 👼🏼.”

Fans were touched by Lottie’s sweet message and quickly shared their condolences in the comments section. “Sending all of my love, I’m heartbroken for you,” said one fan. Another said, “Oh Lottie, I’m so sorry. I can’t imagine. Sending you so much love.” A third couldn’t help but admire her, saying, “[You’re] the most amazing big sister to those girls!”

Félicité passed away on March 14 after an apparent heart attack. Louis has yet to speak out about the death of his sister, though a source told In Touch that he’s been “inconsolable” after learning of the tragic news. We wish the whole family peace in this heartbreaking time.
