The co-hosts are back on the show next week after taking time off for summer - and bosses are reportedly considering big changes to the scheduling.
According to The Mirror, ITV could extend the programme by as much as an hour.
This Morning will be on as normal at 10:30am on Monday (02.09.19), but the changes could be made as early as some point next week.
The publication reported that extending This Morning would fill the gap left by The Jeremy Kyle Show, which was axed earlier this year after guest Steve Dymond took his own life shortly after filming an episode.
It is still undecided what will fill that slot.
It is believed that This Morning could be switched up to start at 9.30am, after Lorraine, and end at 12.30pm.
But a spokesperson for ITV told the Daily Star that a decision on what could fill the free slot had not yet been made.
They told the paper: "It is still undecided what will fill that slot. It will be business as usual on Monday."
While Phil and Holly have been away, a number of presenters have filled in for them.
Regulars Eamonn Holmes and Ruth Langsford have hosted through the week, with stand-ins including The Saturdays singers Rochelle Humes and Mollie King.
TV's Davina McCall also served as a stand-in while Holly and Phil were away.
She was on last week and viewers were made up to see her reunited with Big Brother star Nikki Grahame, who found fame on the reality show in 2006.
Nikki, who has suffered from anorexia since she was a child, was on to talk about a diet app aimed at kids and urge the audience at home to help get it banned.
But viewers appeared to have other things on their minds, as they rushed to social media to praise Nikki's "amazing" reunion with Davina.
