Saturdays star Rochelle Humes and her JLS husband Marvin are expecting their first child.
The pop star couple, who tied the knot in a lavish ceremony at Blenheim Palace in July, announced their baby news on their respective Twitter pages.
The 23-year-old mother-to- be told her 630,000 followers: "I wanted to be the first to tell you... we have some exciting news to share.
"Marvin and I could not be more thrilled to announce that we are expecting our first child mid next year.
"We have always dreamed of being parents and the news is the best early Christmas present we could have asked for.
"I know Marvin is going to be a great dad and we're so excited to start a family. Thanks for all of your support and lots of love."
Marvin expressed his excitement over becoming a first-time dad by tweeting: "Rochelle and I are soooo excited to tell everyone that we are expecting our first baby. It's absolutely amazing.
"We want to say thank you to everyone for their love and support. It means so much to us. We are over the moon."
It will be the second Saturdays baby after Rochelle's bandmate, Una Healy, had a daughter, Aoife Belle, in March this year.
Celebrity pals have flocked to the microblogging site to congratulate the couple.
Oritse Williams tweeted: "A mini #Marvelle is arriving."
Former Spice Girl Emma Bunton wrote: "Amazing news @RochelleTheSats and @JLSOfficial so excited for you both! It's the best feeling in the world! Big kisses!
