Bosses asked her to cover the presenter on the daytime show, which saw her reunited with her 'Dancing On Ice' co-host Phillip Schofield, but she received a frosty reception from viewers, who branded her a 'bad presenter' and 'wooden'.
Phillip Schofield and Christine Bleakley
"Tuning in to This Morning to see Christine Bleakley... Not pleased #badpresenter," wrote one unhappy Twitter user.
Another tweeted: "Heavy topics on This Morning here and dontttttt get me started on Christine Bleakley standing in for Holly. Travesty. I'm outraged."
"Christine Bleakley is about as wooden as well 2 planks of wood on This Morning, this morning!" another wrote.
"ITV, stop trying to make Christine Bleakley happen. She is NOT going to happen," one user added.
Christine was famously axed from ITV's breakfast show 'Daybreak' in 2011, and viewers have failed to warm to the presenter since she took over Holly's role on 'Dancing On Ice' in 2012, after she quit to host 'The Voice'.
Phillip usually hosts the show with Holly Willoughby
Before the show, Phillip tweeted that Christine was nervous about taking Holly's place on the sofa.
"As @hollywills is on the skive today, I'm presenting with lovely @clbleakley .. Who is very nervous!" he wrote.
However, Christine did receive praise from some viewers, with one writing: "Is this Christine Bleakley's first time on @itvthismorning? Seems to be a very good fit #workingfromhome."
Another said: "Christine is doing a great job! Couldn't tell she was nervous atall #doingagreatjobchristine."
Holly returns to 'This Morning' on Tuesday, as the programme gears up to celebrate it's 25th anniversary on Thursday.
Holly and Phillip, along with Ruth Langsford and Eamonn Holmes, will be joined by original hosts Richard Madeley and Judy Finnegan for a special episode live from the show's first home at Liverpool's Albert Docks.
