Lottie Tomlinson has paid tribute to her late sister Félicité on what would have been her 21st birthday.

Félicité tragically passed away in 2019 at the age of 18, following an accidental drug overdose resulting in a heart attack.

Lottie, who is the younger sister of former One Direction star Louis Tomlinson, took to her Instagram Stories on Monday to mark her beloved sister’s 21st.

She wrote: “My beautiful baby sister and best friend would have been 21 today. Not a day goes by that I don’t miss you. I miss my sister but more so I miss my friend.”

“You were the best person to talk to about everything. I think of what you would have been like today, what you would have been doing.”

“But instead you’re safe with Mama looking after us all from up there. Until we meet again, I will make you proud x,” Lottie concluded.

Lottie’s mother Johannah Deakin passed away in 2016 after battling with leukaemia.

The 23-year-old also reshared a quote by Morgan Harper Nichols, which read: “Going through things you never thought you’d go through will only take you places you never thought you’d get to.”

Lottie, who is dating Caroline Flack’s ex-boyfriend Lewis Burton, has previously opened up about how counselling helped her cope with the loss of her sister.

Speaking on ITV’s Lorraine last year, she said: “I got extra help when my sister died than when my mum died. I want people to know that you can get help.”

“Having not had therapy when my mum died compared to when my sister died, it was such a different kind of grief. I look back and think, I should have just done it the first time.”
