While Una opted for comfortable flats and that easy maternity solution of floaty smock and leggings, Chantelle - there with fiance Alex Reid - was wearing a figure hugging T-shirt and exhausting looking high heeled croc boots. Going for the middle option singer Stacey Solomon was wearing a very trad maternity dress with Peter Pan collar but with high heeled boots.
Irish singer Una, 30, is just a few weeks away from her due date in late March and looking glowing. She visited the event - which showcases all the latest baby and mum products - at London's Excel centre by herself, while her rugby player fiancé Ben Foden prepared for the RBS Six Nations today. She left laden with bags.
She recently revealed that her bump is being edited out of the band's latest video. She said on Friday: "Up and ready for to shoot our new video. Bump will be edited out of the video so our director will be working his camera skills magic today!
"I don't want bump in the video because she will be born when it hits the TV screens so it wouldn't make sense or relevance by then!
"And I am proud of my bump but I'll be even more proud of her when she is out, its not like she's going to be in utero forever!'
Chantelle Houghton, 28, was shopping with her fiancé Alex Reid, Katie Price's ex. The couple's baby - also a girl - is due in May. The couplemade the most of the Baby Show with the former cagefighter complaining they had to get help carrying their goodies to the car. Mind you, he was spotted trying out his buggy folding capabilities.
He tweeted: "Bl**min hell @chantellehought how much stuf u get @TheBabyShow? Got help carrying 2 car now, but I gotta carry it later?"
Stacey Solomon is expecting her second baby - also due in May. She brought up her son Zac, three, as a single mum but is now in a long term relationship with her boyfriend and now fiancé Aaron Barham.
