The singer took to her Instagram to reveal she had jetted off to America without her beau as she works on her music career.
Leigh-Anne, 31, headed across the pond as she kickstarts her solo career, as Little Mix take a break from writing together.
The mother-of-two, who shares twins with her footballer beau Andre, 31, revealed she was flying solo this week.
Posing for a selfie on the plane, she looked downcast as she told her fans that it “sucked” to be heading off alone.
The star appeared make-up free as she posed in her business class seat on the flight to America, captioning the snaps with plane emojis.
She followed up with a series of tweets as she admitted she wanted her “safety net” of her beau Andre and their twin children.
“Long distance sucks,” Leigh-Anne wrote to her followers. “I want my safety net, especially now. Can anyone relate?”
Her fans flooded the comments section to encourage the star, saying it would only make her and Andre “stronger”.
She replied to her follower: “This is so true. I generally feel like we can make it through anything now.”
Leigh-Anne and Andre welcomed their twins, whose names and faces they have never revealed on social media, in August 2021.
It followed the footballer popping the question in 2020, after four years of dating, with a mammoth £40,000 ring.
Earlier this year, it was announced that Leigh-Anne had signed a solo deal with Warner Records as Little Mix announced a hiatus.
She went on to jet to the US in order to embark on her solo career.
However, she previously worried fans after admitting she’s “overwhelmed” and “lonely” out in the States.
“I am so easily overwhelmed… even when I feel like great things are happening, I start to freak out a bit,” she penned on Instagram.
“Still figuring out why I do that. I’m also super family orientated and I forgot how lonely being on the road can be.
“Gratitude is so grounding though. I think about this whenever I get these feelings. Well, there’s your stream of consciousness for the day.”
Her bandmates rushed to the comments section to share the love.
Jade Thirlwall, 30, said: “You deserve it all,” while Perrie Edwards, 29, added: “You deserve the world!!! I will remind you of that every day,”
Her post worried fans, with one writing: “So many years supporting you, we are here for you always.”
Another wrote: “So proud of you Leigh-Anne really can’t wait to hear what you have been working on. So exciting.”
