Kimberley Walsh wants to have four children

Speaking to HELLO! magazine, she said: "It would be lovely for him [Bobby] to have a baby brother or sister.

"I come from a big family - with two sisters and a brother - and assume that he'd like the same."

She added: "I used to be adamant about having four children - until I realised that it's not just about me. I adore being a mum and can't imagine not having more kids."

Meanwhile, Kimberley got engaged to Justin earlier this year after 10 years of dating and, although they're planning to wed next year, she is adamant she's no Bridezilla.

She explained: "I'm very chilled about it. The venue is booked, I have the dress, so the important bits are taken care of. I'm getting very excited - but I'm no Bridezilla."

The brunette beauty is inviting her ex-bandmates Cheryl Fernandez-Versini and Nicola Roberts to be her bridesmaids, along with her two best friends from home, her two sisters and her beau Justin's sister and daughter Chloe.

However, she previously said, despite the many famous faces expected to attend, she will be having a low-key wedding when she ties the knot with her longtime lover.
