While they appear cool as cucumbers when the cameras are rolling, it seems behind the scenes things arenโt so rosy for Today hosts Karl Stefanovic and Sarah Abo.

Everything is allegedly not as smooth sailing as it appears.
(Image: Instagram)A well-placed source has lifted the lid on the โpressureโ currently mounting among the cast and crew, with Karl, 48, and Sarah, 37, finding it the hardest to put on a smile for the cameras as the ratings roll in.
โYou can definitely tell theyโre feeling it. Their banter isnโt as seamless as it was.โ
The source says itโs Sarah whoโs under the most pressure, with the stress of wanting to deliver proving to be too much, despite Karlโs best efforts to reassure her that sheโs doing a good job.
It became apparent during a recent taping of the show, where a strained Sarah seemed noticeably agitated in between takes.
โItโs her first major gig โ sheโs wanted this for so long and she understands how it all works. When things arenโt working, top bosses always look at the new talent,โ the insider adds.

CO-HOST KERFUFFLE
The rumblings follow reports that the showโs constant line-up changes have deterred viewers, with Today averaging an average metro audience of 181,000 viewers compared to rival Sunriseโs 213,000.
Most recently, longtime news journalist Alex Cullen was delegated to presenting sports, while entertainment presenter Brooke Boney stepped into news.
Earlier this year, much-loved co-host Allison Langdon announced sheโd be leaving the show to front A Current Affair, where sheโs helped steer the program to strong ratings success.
Ally was just the latest in a long line of co-hosts whoโve shared the couch with Karl since 2005, with everyone from Tracy Grimshaw, Jessica Rowe, Lisa Wilkinson, Georgie Gardner and Deborah Knight appearing then disappearing through the studioโs revolving door.

Allison Langdon recently left Today to take over from Tracey Grimshaw on A Current Affair.

TV ratings show that Today has remained behind Sunrise this year, with the latter winning the majority of the ratings period so far.
However, a defiant Nine has shut down media reports, saying they are a โdistortion of the old-fashioned and out-of-date overnight ratings systemโ.
โOur team is working brilliantly together and our audience response to the line-up couldnโt be more positive,โ says Nineโs director of morning TV Steve Burling.
Its main competitor, Seven, however thinks differently, with a spokesperson claiming โthe [ratings] numbers donโt lieโ.
While they acknowledged Today was ahead in Brisbane, Sunrise โ which is hosted by David Koch and Natalie Barr โ โhas been number one for 19 years and is number one again this year, across the capital cities and nationallyโ.
