STACEY Solomon is eagerly awaiting the arrival of her new baby - and noone seems more excited than her son Rex.
In an adorable new video posted on Instagram, Stacey shared Rex already playing with his new brother or sister – even when they're inside mummy's tummy.
Sitting on the floor, Rex joked that the baby had kicked him, and would approach Stacey's bump before jumping back to the floor dramatically.
"It bumped me down!!" the three-year-old told mum Stacey, who was heard giggling behind the camera.
"Did it kick you that hard...?" she asked, as Rex approached the bump again, lovingly planting a kiss on Stacey's stomach before he dramatically fell back again.

The heartmelting moment comes just over a week after Stacey surprised everyone with the announcement she was expecting her fifth child.
It will be her and husband Joe Swash's third child together, and sixth overall.
Even Stacey admitted the news came as a shock, later revealing she didn't even realise she was pregnant for the first months.
She said: “We really wanted it to ourselves for the beginning bit, but we missed the beginning bit if that makes sense.
“We didn’t have to keep it a secret for 8 months because we didn’t know for 8 months.
“My periods were irregular from breastfeeding, we were planning a wedding then getting married, and then just crazy life and it honestly didn’t register.”
Now it's all systems go - with Stacey admitting she's worried the baby's nursery won't be done in time for the little one's arrival.
