Lottie, 26 - who is the sister of One Direction Louis Tomlinson - was travelling to Abu Dhabi with her fiancé Lewis Burton and their two young children, Lucky, 2, and baby Flossie.

“I felt quite ill on the way here, on the plane, really bad stomach pains,” she explained, in a video posted to her Instagram story.

“I started throwing up when I got here and long story short I went to the doctor and they put me on a drip - but it wasn't helping with the pain, the stomach pains,” she added.

“So they sent me to hospital where they discovered that I had appendicitis so I needed surgery straight away, so last night I had surgery to remove my appendix and it all went well, so I'm just now recovering.

“But I'm so grateful to all the nurses and doctors that have looked after me and I'm hoping that I can make a quick recovery.”

She also uploaded a photo of Lewis, with their two-year-old daughter Lucky in hospital, captioning the snap: “Hopefully I can make a speedy recovery and enjoy our last few days here.”

And it sounds like the reality star, 28, has been welcomed with open arms into the family of the former One Direction singer, 33.

“Yeah, she is amazing and they are really happy. I’m really happy for him,” Lottie told The Mirror at a launch for her newest beauty venture.

She also joked to the publication that Zara might “hopefully” be up for babysitting duties.

Lottie is a make-up artist, model, author and businesswoman with the self-tanning company, Tanologist.

The 26-year-old has suffered the loss of two close family members in recent years - her mother, Johannah Deakin, died from leukaemia in 2016 aged 43, and her sister Felicité just two years later at the age of 18.

She told the Mirror that being with her family, such as her siblings, was how she copes with grief.

“I feel like being with my family is just the best therapy for me,” she shared.

“That's all I've ever wanted and now that I've finally got that, it brings me so much comfort and it makes me feel closer to the people I've lost. It's been like a healing thing for me.”
