Cheryl was supported by her ex-boyfriend Liam Payne as she made a rare red carpet appearance over the weekend.
The former Girls Aloud singer, 39, attended the event held at The Londoner Hotel, which was thrown in memory of the late Sarah Harding, who died age 39 last year following a battle with breast cancer.
Cheryl was joined by her former bandmates Nadine Coyle, 37, Nicola Roberts , 37, and Kimberley Walsh, 40, to host the charity fundraiser, called The Primose Ball, on Saturday evening.
