Doting mum Billie just couldn't resist sharing a snap of her mini-me in her swimming costume - and she looked absolutely adorable!
Sporting a cute heart-printed swimsuit with a red rose design, Nelly looked super-stylish for her first ever dip in the pool. Accompanied by mum, who looked just as fabulous in a low-cut red number, the girls enjoyed a nice afternoon swim.
Captioning her photo, Billie said: "Me and my little Nelly going swimming..."
Making sure she didn't miss out on all the fun, Billie's sister Sam was there to offer a helping hand while Nelly was in the water.
Joining Billie and her baby girl, Sam tweeted: "We Just took baby Nelly to her first ever swimming session #waterbaby xxxx she loved it."
Earlier this week, Nelly joined Billie for a starring role on TOWIE during Wednesday night's episode (15 October).
Enjoying a cuddle with TOWIE newbie Tommy Mallet, Nelly listened in as Tommy told Billie all about his plans to take co-star Georgia Kousoulou out on a first date.
But, as much as we loved seeing little Nelly on camera, from now on her appearances will be a rare treat.
Despite saying she is happy for Nelly to occasionally be on the show, Billie and her fiancé Greg Shepherd do not want their daughter to become a regular castmember.
New parents Billie and Greg welcomed Nelly - their first child together - back in July.
