The former S Club 7 singer and her husband Alex Bourne – who already have a three-year-old daughter Amelie together – welcomed a second daughter last night and took to their Twitter accounts to announce the happy news.

Alex, 36, wrote: “Delighted to announce the safe arrival of our gorgeous little girl! @MsRachelStevens and baby both really well. Amelie happy and ‘cited’ x.”

And although the pair have yet to name the little one, they revealed that they are “totally smitten” with the newborn, who weight 7lbs 7oz.

“Needless to say, we’re all super excited, especially Amelie who is looking forward to meeting her new little brother or sister.”

Rachel and Alex have been married for four years.
