Girls Aloud stars party in London

Cheryl Cole enjoyed a girly night out with BFFs Kimberley Walsh and Nicola Roberts over the weekend.

The singer, 30, shared a cute picture of her and Nicola touching pregnant Kimberley‘s growing baby bump as they celebrated a friend’s birthday together.

‘3 woman and a baby 😁💋👯😘,’ Cheryl captioned the sweet Instagram snap.

Mum-to-be Kimberley, 32, clearly appreciated having her pals take care of her and told Twitter fans: ‘My girls were looking after me tonight 😍’

The Girls Aloud stars partied at The Box nightclub in London for choreographer Beth Donnan‘s 40th and posed for an adorable photo with the birthday girl.

‘Sex in the city. Friends forever. No place I’d rather be,’ Nicola, 28, posted with the shot.

Nicola continued to praise her best mates and wrote: ‘I ❤️ these 2 👸👸 of mine 😻’

All three ladies looking stunning for their evening out – Cheryl flaunted her tanned pins in a short leather skirt and grey vest, Nicola donned a classic black dress and Kimberley showed off her bump in a pretty floral jumpsuit.
