Meanwhile, TV presenter Jenni Falconer looked in high spirits at the bash where she wore a light yellow cut out dress.
Kimberley recently spoke to MailOnline about her long lasting friendship with Nicola and fellow Girls Aloud star Cheryl from their time in the group.
She said: ‘I think it’s kind of incredible really it’s been such a long time since the beginning of Girls Aloud, what, 17 years or so? Now we’re in a whole new phase of our lives.’
Kimberley went on to add that she has merged all her friends in the ‘mummy zone’ and that they all get together for special events.

She added: ‘As I am with all my friends that I’ve grown up with, we’re all in that mummy zone.
‘We all kind of merge together, all of my friends know each other, we all get together for the kids’ birthdays and stuff. It’s just a new phase of life, it’s lovely to do it together.’
Talking about whether having kids has deepened her friendship with Cheryl and Nicola, she continued: ‘I think kids do that anyway, they put you on a different emotional level, I think it’s just nice that all mums have an understanding.

‘It’s when you become a mum, you become part of a club, you understand what that means… it does take it to another level I guess.’
Kimberley also joked that the reality of her meets up, especially with Nicola, result in her being on ‘childcare duties’ as she shared a funny story from one of their recent get togethers.
She said: ‘It’s lovely catching up, Nicola came over for a little spa date, we had a facial treatment at mine, but I’m not sure it was quite as relaxing as she was hoping for. The reality was she was on childcare duties while I had my facial.
‘I could hear what was going on with my eyes closed and Bobby was making her do flying in the air, jumping on her back like Superman, making her run around, playing guns and all sorts… so I’m not sure it was the most relaxing spa date she has ever had.’
