Rochelle Humes is worried her baby is going to be "lanky".
The Saturdays singer is expecting her first child with JLS star husband Marvin Humes, due in May, and as they are both tall she thinks the baby will get their genes.
Rochelle said on Daybreak: "The poor thing will be quite lanky I think - the tallies."
Bandmate Frankie Sandford chipped in: "It's going to have the most perfect skin."
Rochelle, who revealed she is about eight weeks away from her due date, admitted she is enjoying being pregnant because the band always offer her a seat.
She joked: "I always get the seat which is great. So I'm considering putting a cushion up afterwards. Whenever there's a seat they're like 'you sit down'."
Bandmate Una Healy recently celebrated the first birthday of her daughter Aiofe with her husband, rugby player Ben Foden.
Una revealed: "She was Minnie Mouse for the day. It was a nice quiet intimate family party. Just me, Ben and a couple of friends.
It was so funny, when we sang her Happy Birthday, she started roaring crying. She was so scared of all these people singing her Happy Birthday, she got really embarrassed."
