TOWIE's Billie revealed her newborn's name this evening (20 July) during the latest episode of the ITV2 reality show.
While the tot made her first appearance on screen, Billie addressed her little one as 'Nelly' while chatting to Gemma Collins and Ferne McCann.
The trio had been discussing that James 'Arg' Argent and Lydia Bright had slept together, when Gemma - who previously had a fling with Arg - broke down in tears.
Comforting her friend with one arm and holding her daughter in the other, Billie said: "Gem, why are you crying? Come on, Nellie doesn't want to see you upset."
Struggling to hold back tears, Gemma insisted: "I'm crying because of the baby...she's beautiful."
Billie, 24, gave birth to her first child on 9 July. She was supported in the delivery suite by both fiancé Greg Shepherd and younger sister Sam, who has been a doting aunt ever since!
Reveal was first to report the happy news, with a rep telling us: "We would like to announce our client Billie Faiers has given birth to a baby girl. Mother and baby are doing well."
Ever since then, it's been clear that Billie is enjoying every minute of motherhood!
Last week, she described her newborn as "mummy's little angel" and said: "Having cuddles with my favourite person in the world."
The blonde boutique owner announced her pregnancy back in January, letting it play out on TOWIE. In an episode of the ITV2 show earlier this year, we discovered Billie was expecting a baby girl when she cut into a pink cake at a cast party - pink for a baby girl. Aww!
Billie's had a pretty a-mazing year so far.
Not only has she become a mum for the first time, but she became engaged to businessman Greg during a romantic holiday to the Maldives earlier this year, and launched a children's clothing company called Jam Kidswear.
We wonder what's next?!
