The vocal powerhouse has landed herself a role in upcoming British romantic comedy Boxing Day.
According to reports, which have not been denied by Little Mix's team, Leigh-Anne, 29, will star alongside Golden Globe and BAFTA-winner Marianne Jean-Baptiste in the role.
The film is being touted as the first UK Christmas film to feature an all-black cast.
Actor Aml Ameen is set to make his directing debut with the film.
Talking about the project, Ameen said: "It is such an honour to be teaming up with Warner Bros.
"Pictures, Film4 and BFI to bring Black British Culture to the world in this universal holiday rom-com.
"It’s long been a dream of mine to capture films that reflect the wonderfully multi-cultural city that raised me while sharing stories from the diary of my life."
A rep for Little Mix has bene contacted by Daily Star Online for comment.
The news comes just days after Jesy Nelson took a break for the band.
In a short statement, reps for the chart-topper confirmed Jesy would be "taking an extended break" from the group for private medical reasons.
In the weeks prior to the announcement, Jesy was forced to pull out of both the final of Little Mix: The Search and hosting and performing at the 2020 MTV Europe Music Awards.
Despite Jesy's absence, Perrie Edwards, Jade Thirlwall and Leigh-Anne Pinnock continued to perform and host the show.
A statement at the time read: "Jesy is unwell and will not be appearing on tonight's final of Little Mix The Search. She will also not be hosting or performing at tomorrow's MTV EMAs."
The same weekend Little Mix released their sixth album Confetti.
Jesy also didn't appear in a pre-recorded Little Mix sketch with children's TV duo Dick and Dom on Children In Need which aired last Friday.
Earlier this month, fans of the chart-topping band expressed their concern after signed albums they had ordered online arrived without Jesy's signature.
