In the months since, the pair have been reportedly "leaning on each other" an insider source told our sister publication Woman's Day.
"Carrie Bickmore has always found comfort in Tommy," they said.
"But this time is different - they're both single! She feels like there could be something."
"He just makes her laugh and they have so much fun together."
Carrie's ex Chris also hasn't helped quell the rumour mill, taking to his Instagram stories and sharing a cryptic image of Carrie and Tommy together late March, with no caption, before swiftly deleting it six hours later.

Tommy is also keen to "make things work" with his friend and potential lover but is hesitant to make things awkward at their workplace.
"The last thing he wants to do is jepoardise that gig now that he's pulled back from The Project," an insider says.
Despite this, the firm friends haven't done much to squash rumours, getting up close and personal at a number of industry events.
And whilst neither Tommy nor Carrie has opted to comment on their rumoured romance, comedian, and LegoMasters host - of all people - Hamish Blake has!
During an appearance on the Kyle and Jackie O show, Hamish was quizzed given he is best buddies with Tommy's roommate John.
"You'd know this, is Tommy Little having an affair with Carrie Bickmore," Kyle Sandilands bluntly asked.
Hamish was quick to say no.
"John is my best mate and he is terrible at keeping secrets so, there's no way, I definitely would have heard about it," Hamish laughed.
Unfortunately for fans, less than a week later, Tommy himself confirmed that he was "currently single" whilst live on 2DAY FM's Hughesy, Ed & Erin.
The comedian also confirmed that the only dating app he was currently on was the exclusive 'celebrity only' site Raya.
