The former TOWIE stars announced their pregnancies within days of each other, with Billi sharing her and fiancé Andy Carroll’s happy news on Christmas Day.

This week the friends stepped out together and shared a picture showing off both of their blossoming bumps.

Alongside the snap posted to Instagram, Cara wrote: “Battle of the bumps #Roka @billimicklow [sic]”

Cara also joked that pregnancy has put romance with her partner to the back of her mind.

Sharing a picture of her glam bedroom, she wrote: “New cuddling partner tonight… Don’t think someone will be pleased #pregnancypillow [sic]”

When Billi announced her pregnancy, Cara took to Instagram to gush over being pregnant at the same time as her best friend.

She wrote: “So finally I can share the amazing news that my beautiful best friend @billimucklow and husband to be @andycarroll are expecting… 2014 has been your year my darling and I love you.

“Can’t wait to meet this little mister. Hopefully they get Andy’s long legs and your looks.”

Billi and West ham footballer Andy announced their engagement in Novmeber last year.
