The reality TV star and boutique owner, 25, spent the morning of Mothering Sunday (15 March) with her daughter Nelly and shared a cute new picture with her fans.
In the adorable snap, a bare-faced Billie is lying in bed with her eight-month-old baby who is looking at her mummy with a big smile on her face! Sooo sweet!
Alongside the photo, Billie wrote a touching message to all mum's like herself.
She said: "Happy Mother's Day to all of the wonderful mummy's... I hope you all have a lovely day... So happy spending my morning having cuddles with my beautiful nelly noo."
She also posted a personal tribute to her own mum.
Sharing a photo of herself and sister Sam when they were younger with Suzanne, Billie wrote: "Happy Mother's Day my beautiful mummy! Thank you for always being there for me and being the most amazing nanny to nelly... We love you so much."
Billie was recently "honoured" to be named Celebrity Mum of the Year.
She scooped the title in the icelolly.com contest over the likes of Katie Price, Frankie Bridge and Holly Willoughby.
Billie and partner Greg Shepherd welcomed little Nelly last July, shortly after announcing their engagement.
Nelly has made a handful of appearances on TOWIE.
