While some fans called Carrie out for her "TMI" post, most saw the funny side and praised the presenter for getting on with her job.
"And this why everyone loves Carrie.❤️" wrote one fan.
Although Carrie's radio co-host, Tommy Little - who was rushed to hospital for a mystery illness least week - claimed she was "upping the ante" in the sickness stakes, joking: "You couldn’t just let me be the sick one could you?! Oh no, you had to go and up the ante and s**t yourself on live TV!"
Carrie returned to host The Project last week after taking eight months off for maternity leave after having baby Adelaide in December.
The mum-of-three shares her seven-month-old daughter with her partner Chris Walker.
Carrie has been a presenter on The Project since the Channel Ten show debuted in 2009 as The 7pm Project.
