The mum-of-four, 35, shared the snap with her 1.81 million Twitter followers early this morning.
Featuring her youngest son Jett, fast asleep and bundled up in blankets, she captioned the image: "My gorgeous little baby boy morning sleep".
Her fans couldn't help but coo over the littlest member of Katie Price's family, dubbing the baby boy as "so precious", "a little cutie" and saying that they "bet he's got that lush baby smell they all have on a morning."
The picture comes shortly after the former glamour model shared a series of amazing family snaps with her other three children, eldest son Harvey and Princess and Junior, her children from her marriage to Peter Andre.
The photos, which she dubbed as "perfect" family shots, also featured husband Kieran Hayler.
At the time, many of her followers asked where baby Jett was, so we imagine they'll be pleased to see the little tot at last!
Meanwhile, Katie has been gushing about becoming a mother for the fourth time, admitting she loves having a baby and will not be worrying about getting her pre-baby body back:
This comment, of course, came after fans commented on Katie's lack of stretch marks. Which was inspired by this photo the former glamour model shared of her spray tan.
While many slammed the image for being tasteless and "attention-seeking", plenty of Katie's fans took the opportunity to check out her post-baby body - and praised the mum-of-four for her toned legs and lack of stretch marks.
What do you think of the image?
