Lucy Mecklenburgh, Gemma Collins, Ferne McCann and more wore their brightest spring outfits as they arrived to celebrate the star's first pregnancy.
Gemma Collins wore a floor length bright pink dress and her hair loose, whilst Lucy Mecklenburgh teamed a yellow mini dress with nude heels and a monochrome jacket.
Ferne McCann also looked chic in a white pencil skirt and crop top, teamed with strappy heels and a pink clutch.
Billie, who is due to give birth this summer, recently spoke of the terrifying moment she collapsed at a bar whilst six months pregnant, and worried that she might be losing her baby when she couldn't feel it moving a day later.
After the ordeal, the star has been told by doctor's to take it easy, as they investigate her for a possible irregular heartbeat.
On Sunday she tweeted: 'Looking forward to my Baby shower today….'
Lucy Mecklenburgh also took to the social media site to congratulate her pal, writing: 'Lovely baby shower hosted by the yummiest mummy in Essex @BillieFaiers Nice 2 see my girlies @SamanthaFaiers @Ffernemccann @missgemcollins.'
24-year-old Billie is expecting her first child with her fiancé Greg Shepherd.
