Billie, who welcomed Nelly with fiancé Greg Shepherd in July, shared the cute close-up snap with fans on Instagram last night (13 October).
Captioning the photo, she said: "Cuddles with my little beauty."
With her hair styled in a top knot, Billie protectively wrapped her arms around the little tot, who was fast asleep - aww!
As a first time parent, Billie is loving motherhood, and just last week she couldn't stop gushing about her baby girl.
Speaking exclusively to Reveal, she said: "It's going really well. I'm really enjoying being a mum. Now it's really nice because she's starting to interact a little bit more. I chat to her all day and she kind of talks back to me with baby talk! It's really funny. She's really cute and she's such a happy baby as well."
The new series of TOWIE kicked off last week with two Ibiza specials, and it continues on Wednesday night with the gang back in Essex. Billie didn't join her co-stars in Ibiza, but rest assured, as she is back in tomorrow night's episode!
"Being a new mum, you just couldn't possibly leave your child for that amount of time," Billie told us. "I didn't feel like I missed out [in Ibiza]. Obviously I did catch up on some of the gossip. Plus, the weather was crap so I wasn't missing too much!"
TOWIE continues tomorrow night (Wednesday 15 October) at 10pm on ITVBe.
