And it seems that their celebrity pals are just as excited as us that a mini Saturday or JLS member is on its way.
Rochelle revealed she’s pregnant on her Twitter page, saying: “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 dreamt 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 your support and lots of love, Rochelle x.” (sic)
Once we’d blubbed a little, it was Marvin’s turn to go all mushy. He took to JLS’ official Twitter account to say: “Rochelle and I are SOOOO excited to tell everyone that we are expecting our first baby!!! It is absolutely amazing!
“Baby is due middle of next year and all is great!! We want to say thank you to everyone for their love and support…it means so much to us!!! We are over the moon. Love Marv x.” (sic)
