Lily flaunted her platinum blonde locks in a slick bob and completed her look with matching sky-high heels.

The Pillowman is Lily’s latest acting role after appearing as Jenny in 2:22 A Ghost Story last year.

She has taken on the role of Katurian, a writer of disturbingly violent stories imprisoned by a totalitarian state.

However, the star admits that her work schedule has disrupted her relationship with her children – who she hasn’t spoken to in weeks.

She shares a home in New York City with husband David Harbor and her daughters, Ethel, 11, and Marnie, 10, from her former marriage to builder Sam Cooper.

But her starring role in a revival of Martin McDonagh’s The Pillowman at London’s Duke Of York Theater has kept her away from loved ones throughout its sustained three-month run.

Taking to Instagram on Monday, Lily admitted that it made her battle loneliness, exacerbated by attending her kids at a summer camp in the United States.

She wrote, “Hello Monday. 1 month to go from The Pillowman. I miss my house, I miss my bubbas who are both at summer camp, I haven’t even spoken to them in 2 weeks! tired and lonely, but the Banya always manages to get my blood going and cheer me up.”

The singer recently appeared on This Morning alongside her co-star Steve Pemberton to discuss the production.

She said, “There’s a little bit of violence in it. She’s an artist and a writer and that’s something I’ve identified with. She certainly pushes boundaries. There was much for me to draw from.’

Lily, who is used to performing as a singer, shared how she likes the fixed character of the leading role in a theater production.

She said, “I really like the routine of it all. I like to be in one place. It’s nice not to get on a bus and go to the next destination.’

The role is a serious undertaking for Lily, as she does not leave the stage for the entire duration of the play.

The Pillowman will only run for a limited time and will end in early September.
