The singer posted a photo of her stomach to Instagram with the caption: “So happy to be on this wild trip with my soul mate.” Me + Him = You. We can’t wait to meet you baby Ox! “
A second photo showed Liverpool footballer Oxlade-Chamberlain cradling his partner’s baby bump.
Edwards and Oxlade-Chamberlain have been in a relationship since early 2017.
The England player posted on his own page: ‘Has anyone had any advice on how to change diapers? I am so thankful and excited to be a dad. Bring on the sleepless nights. “
Edwards is the second member of Small mix to reveal she’s pregnant this month, after Leigh-Anne Pinnock announced that she was waiting with footballer fiance Andre Gray, who plays for Watford.
Reacting to his bandmate’s pregnancy, Pinnock commented on Instagram, “Arghhhhhhhh so so happy for both of you! And so happy that we can make this trip together! I love you so much. “
Little Mix third member Jade Thirwell said, “Beaming for you two… I’m the luckiest aunt in the world! I love you x. “
The trio have been part of Little Mix since the group formed in 2011 on The X Factor. Jesy Nelson left the group late last year, claiming being a member had “Wreaked havoc” on his mental health.
Other celebrities were quick to congratulate Edwards.
Love Island host and new mom Laura Whitmore commented on the post, “Yes mom. “
Vicky Pattison, who rose to fame on Geordie Shore, said, “AAAAAARRRRGGHHHH !!!! Oh buddy !!! Congratulations my God !!! “.
Oxlade-Chamberlain has been praised for his social media post by Newcastle striker Callum Wilson, former Arsenal teammate Calum Chambers and fellow Liverpool star Andy Robertson.
