Una Foden has announced that she's expecting her second child with her rugby player husband Ben Foden.
She posted a photo of their two-year-old daughter Aoife wearing a T-shirt emblazoned with the words: 'I'm going to be a big sister'.
"I know lots of people have been guessing and Ben and I can now confirm that Aoife is going to have a baby brother or sister next year!!! We're all very happy," Una captioned the snap.
Una and Ben's second child will be the fourth Saturdays baby, as Una's band mates Rochelle and Frankie both became mums in the last couple of years.
Speaking to Parentdish last year, Una revealed that her and Ben disagree over whether they'd like a boy or a girl next:
"I think Ben would like a boy, but I like the idea of two little girls," she said. "I know where I am with girls. One at home and four at work..."
Una made her pregnancy announcement on the same day that Clarence House confirmed that the Duchess of Cambridge is pregnant with her second baby.
Funnily enough, Una told Parentdish that she got swept up in Royal Baby fever when Kate was pregnant with Prince George.
"It was very exciting! The pressure on Kate must have been out of this world, and then she came out cool as a cucumber with baby George looking fabulous!" she said.
This time around Una can enjoy reading all about Kate's condition as her own pregnancy progresses.
