Rochelle Humes has confessed she struggled to keep her pregnancy a secret from her Saturdays bandmates.
The 23-year-old and her husband, JLS singer Marvin, announced in November that they are expecting their first baby together, but had to keep the good news quiet at first.
Rochelle - who has been busy filming her E! Entertainment reality show Chasing The Saturdays in Los Angeles - said: "Oh yeah, it's the hardest secret to keep anyway, because you have to wait to the sort of safe point and being away from home it was definitely strange.
"The girls would be saying, 'Let's go out for sushi tonight' and I'm like the biggest leader for that, I'm always saying, 'Let's do something' but I'd go and disappear into my room."
She added: "They all had the chat without me and outed me, they were like, 'Are you pregnant?'"
The mum-to-be also said she was coping well with the girlband's hectic schedule.
"I don't know any different. It's my first experience of being pregnant. There's definitely a lot going on. We're the busiest we've ever been in our whole career. But it's kicking and it's going for it in there."
And Rochelle insisted she won't be letting the TV cameras into the delivery room.
She said: "No. That's something that... no I don't want to see that!"
