Frankie Bridge is expecting her second baby with footballer husband Wayne.
The Saturdays singer, 25, who was runner-up in this year's Strictly Come Dancing, announced on Twitter this evening that she is to become a mother again later this year.
The couple's first child, a son who they named Parker, was born in October 2013.
She tweeted tonight: "So excited to tell you that Wayne & I are expecting another baby later this year. We can't wait for Parker to have a little brother or sister."

The pop star was a firm favourite with the public on Strictly but was forced to pull out of the show's forthcoming UK tour due to illness.
A tour organiser said Bridge is currently suffering with severe sickness known as hyperemesis gravidarum, which has also affected the Duchess of Cambridge during her pregnancies.
The spokesman said: "We completely respect Frankie's decision; a safe pregnancy is the priority. On behalf of the whole cast and crew, we send Frankie our love and very best wishes - we will miss her."
In a statement issued through the tour, Bridge said: "Wayne and I are delighted to announce that we are expecting our second baby. It is very early days, but we couldn't be happier and Parker will make a wonderful big brother.
<blockquote class="twitter-tweet" data-partner="tweetdeck">Sadly I'm really unwell with my pregnancy and won't be able to take part in the Strictly tour. I'm SO sorry. I was so looking forward to it.— Francesca Bridge (@FrankieTheSats) <a rel="nofollow" target="_blank" href="https://twitter.com/FrankieTheSats/status/553264965206175747" class="body-link" data-vars-item-name="BL-118156-https://twitter.com/FrankieTheSats/status/553264965206175747" data-vars-event-id="c23">January 8, 2015</a>
"Although this is such an incredible time for us as a family, due to health reasons I am sadly unable to go on the Strictly tour as planned.
"I'm devastated that I'm missing out, as I loved Strictly so much and was so looking forward to joining everyone again in all those fabulous arenas. Thanks for the warm messages I've already received, they are really appreciated."
The producers will announce tomorrow the name of a new celebrity performing in the arena tour.
Bridge's 34-year-old husband retired from football last year, having played for clubs including Chelsea, Manchester City and Southampton, and was also capped for England.
