Awkward reunion between Deb Knight and Karl Stefanovic as they co-host Nine's ...

Deborah Knight returned to co-host the Today show on Monday, nine months after leaving the program.

The 47-year-old journalist was filling in for Allison Langdon alongside Karl Stefanovic, with whom she reportedly has a strained relationship.

As viewers tuned in just after 5:30am, Deborah didn't directly mention the fact she used to be Today's full-time anchor, but did joke that she was 'getting a refresher'.

Karl was sacked from Today while on his honeymoon in December 2018. Deborah was subsequently announced as his replacement, alongside Georgie Gardner.

But in November 2019, Channel Nine announced that both female anchors were being axed due to low ratings, and Karl was being reinstated alongside Allison.  

'Nice to see you again,' Karl told Deborah at the start of Monday's show, adding: 'Ally is on a well-deserved week holiday. Deb is in for the week.'

Their friendly on-air exchange comes almost two years after Karl was accused of comparing Deborah to a horror film character in January 2019.

KIIS FM host Kyle Sandilands claimed on air at the time that Karl had sent him a photo of Freddy Krueger via text message after he'd invited him to join Deborah and Georgie for an in-studio interview.

Freddy is the antagonist from the Nightmare on Elm Street series of horror films.
