The pop star announced the happy news yesterday on Twitter saying, "Yes I am having a new lovely baby, children are such a blessing and I'm grateful to god for my new little gift."
She posted her news alongside a picture of two swans which read, "There's a little heart beating next to mine."
She also shared a second image of a baby's sonogram, alongside a poem with one line reading, “Oh sweet child kicking up your heels, it is our little secret that only I can feel.”
Rebecca is already a mother of two children - Lillie May and Karl - from a previous relationship.
The singer has so far not publically revealed the identity of the baby's father, but has previously said she is dating a man she has known for several years.
Speaking about her partner recently, she said, “We've been together a year now. He's lovely and he looks after the kids."
