Cheryl has increased her security detail after “disturbing” messages were left for her by a stalker during her stint in the West End.
The 39-year-old former Girls Aloud star is currently in the critically acclaimed 2:22 A Ghost Story at London’s Lyric Theatre.
Her critically acclaimed performances in the nightly show were apparently tainted by "disgusting" messages left for her at the venue.
"There’s at least one nutter who has been sending some pretty disgusting and disturbing messages," a source told The Sun.
"She hasn’t been shown them but they’re included with the flowers people leave after performances.
"Cheryl has enough to think about on stage to a packed theatre each night without having to think about that too, but steps have been taken to ramp up security and put her mind at rest."
The mother-of-one is said to now have a team of security guards around her.
She also reportedly has a car waiting for her directly outside the stage door to take her straight to her Buckinghamshire home after the show.
The star has been praised for her role as Jenny in the show.
Co-star and ex Eastenders actor Jake Wood, 50, said: "It’s quite remarkable to see someone who has never acted before come on stage at the West End, she is in the spotlight, with all that pressure.
"It’s quite amazing how resilient she is, really. And she is giving amazing performances, people are blown away by how good she is."
Cheryl took over from former Love Island host Laura Whitmore when she joined the play in January.
Lily Allen also had the role in 2021.
Cheryl’s stint in the show is set to finish on April 23.
