The gorgeous tot – who turns one later this year – joins her glamorous mum and co-stars Ferne McCann and Lydia Bright in a scene to air on tonight's episode.
Nelly has only made a handful of appearances in the reality show since her birth, with Billie preferring to keep her largely away from the ITVBe cameras.
She was in Tenerife with Billie and the girls earlier this month but was not in any of the scenes aired on the TOWIE series premiere on Sunday night (22 February).
The more Nelly the better we say, though!
Nelly is Billie's first child with fiancé Greg Shepherd, who has always shied away from the limelight.
She's the first - and only - TOWIE baby to feature on the reality show. Although co-star Dan Osborne is dad to son Teddy, one, and newborn baby Ella, neither have been filmed… although Ella was only born last week so let's give her some time!
TOWIE airs at 10pm on ITVBE.
