The Essex star took to Instagram to post the mega cute photo that's racked up an impressive 17,985 likes from fans.
In the picture, Tommy can be seen playfully poking his tongue at the camera while wearing a cosy black jumper. Meanwhile, little Nelly has her eyes shut for the snap - bless! Maybe the flash was all a bit too much?
Also, check out her super sweet floral pyjamas.
We reckon Tommy had popped over to Billie's for a catch up and to see how his pal is getting on with her second pregnancy. Last month, Billie took to Instagram to reveal she's expecting baby number two with fiancé Greg Shepherd. The post, which included a lovely family photo, simply read: "And then there were four".
Potentially all this talk of babies could be making Tommy a teeny bit broody... The clothes designer, who is loved-up with TOWIE co-star Georgia Kousoulou, has always been pretty vocal about how eager he is to start a family.
But it's not just one or two he wants, oh no! In the past, Tommy has revealed he wants SEVEN children. Gulp. Talking to Georgia in a scene on TOWIE, he admitted: "I want seven, I want an army."
However, it looks like they won't be starting their brood quite yet.
Last month, Georgia spoke to the Daily Star Online about Billie's pregnancy, declaring she's over the moon for her friend, but isn't ready to become a mum herself anytime soon.
The pretty blonde said: "God no [I'm not broody]. I'm so happy for Billie but I'm not ready for that yet. I'm happy concentrating on my career right now."
Despite discussing kids in the past, Georgia has told Tommy she won't be getting pregnant until they're engaged first. Tommy, we guess the ball's in your court now.
Give us a TOWIE wedding!
