The former Girls Aloud star recently rocked silver grey hair during a photoshoot, and she also got a fancy pedi for the occasion.
We've been loving black nail polish for a while now, and Sarah glammed up her sultry shade with a cute dalmatian-inspired print.
The best thing about this look? It's really easy to recreate!
1. When painting your talons with such a dark shade, always use a base coat. This will avoid the colour staining your tootsies. Slick on Revlon Quick Dry Base Coat, £6.49, and allow to dry.
2. Take your favourite black nail polish (try Miss Sporty Lasting Colour Nail Polish in Fatal Black, £1.99) and coat each nail as evenly as possible. Wait for it to dry, then apply another coat.
Black is a pretty tricky colour to perfect, so keep a cotton bud dipped in nail polish remover on hand to clean up any mistakes.
3. Once your black polish is totally dry, take a white nail art pen (we like Models Own Nail Art Pen in White, £6) and decorate your nails by dotting all over. Make it totally random and don't be too neat!
4. Make sure your polish is 100% dry, then seal your work with a long-wearing top coat, such as Rimmel London Finishing Touch Superwear Nail Top Coat, £4.49.
Pair with black peep-toe heels for an evening look with an edge!
