Pregnant Rochelle Humes squeezes into leopard print catsuit, no sign of baby bump!

We'd quite frankly never be able to squeeze ourselves into a leopard print catsuit (well unless we wanted our mince pie baby to be on show to the world).

But The Saturdays star Rochelle Humes has got all of our admiration this morning after she attempted to look FLAWLESS in a skin tight onesie last night despite being PREGNANT.

Marvin Humes' stunning wife squeezed herself into the daring outfit all in the name of fancy dress last night - as she channelled Spice Girl Mel B.

Roch and her JLS hubby headed to a 90s theme star party last night, where her The Sats band member Frankie Sandford joined her as Victoria Beckham.

Frankie fooled us into thinking she'd done away with her short crop in favour of a 90s bob.

But the singer - who was at the bash with her footballer boyfriend Wayne Bridge - had merely donned a wig to channel Posh Spice's finest era.

Meanwhile Rochelle's husband Marvin went as MC Hammer for the occasion.

He tweeted from the JLS account: "MC Hammer and Scary Spice dating back in the 90's!!! Marv x"

And by the sounds of things Rochelle is struggling a bit with the whole no drinking thing whilst pregnant. She posted: "Oh to be the sober one".

Adding when she got home: "Nice lay in tomorrow night world!! 💋❤😍 fancy dress is fun! It's always funny to see who goes the hardest! Marv was a contender lol x x"
