Danielle attended Carol's baby shower yesterday (7 October) but it was quite clear which pregnant lady will be heading to the labour ward first.
Posing together at the event, the BFFs were all smiles as they showed off their growing tummies for the camera.
Danielle, who is expecting her first child - a girl - with husband Kevin Jonas, dressed her small bump in a clingy white T-shirt with pretty gold stud detailing.
She teamed it with a comfy pair of black maternity trousers, kept her hair in big loose curls and added a splash of colour with a red lipstick.
Model Carol, meanwhile, opted for a long-sleeved grey dress with black stripes down the arms and across her big bump.
Posting the picture on Instagram, Danielle had nothing but kind words to say about her friend, who is expecting a baby boy in the coming weeks.
She wrote: "Your shower was beautiful. You are going to to be such a great mum. A baby comes into this world needing to be loved by his parents and he is going to be smothered by it.
"You and Jimmy were made to be together and this baby is the icing on top. #icantwaittomeethim." Aww!
