Lily Allen has hired an £80 (NZ$190)-an-hour personal trainer, for her face.
The 30-year-old star has been training at a specialist gym where clients are put through punishing regimes that act like a "natural Botox" to fight off ageing.
Lily posted a photograph of herself at the Face Gym in central London alongside the caption: "Putting in the hours @face_gym #tiring (sic)."
Customers are offered half-hour £40 (NZ$95) treatments which include a warm-up, cardio, advanced training and a cool down.
They can also seek help for specific problem areas including the scalp, brows, cheeks and jaw.
