Another one on the way: Kimberley Walsh announces she's pregnant

Girls Aloud singer Kimberley Walsh has announced that she is pregnant.

The 32-year-old revealed on Twitter that she is expecting her first child with boyfriend of 10 years Justin Scott.

"Justin and I are so happy to let you all know we are having a baby!!!" she tweeted. "Couldn't wait to share our lovely news with you all."

Following the announcement, Walsh's Girls Aloud bandmates Cheryl Cole and Nicola Roberts expressed relief that they were finally able to share the news, and congratulated her publicly for the first time.

"@KimberleyJWalsh FINALLY, I thought at one point I was going to burst," Cole tweeted, while Roberts wrote:

"Secrets out!! I am BURSTING with love! Kimberley & Justin are having a baby! I am so happy and so literally beside myself with excitement!!!"

Walsh's news comes just two weeks after fellow Girls Aloud star Nadine Coyle announced the birth of her first daughter.
