Music mogul Simon was left needing emergency surgery on his back after a nasty accident on his electric bike.
Now on the road to recovery and eyeing up a telly return, Simon received the good will of Britain's Got Talent co-hosts and national treasures Ant McPartlin & Declan Donnelly.
Appearing on The One Show, the famous duo chatted about their new book, Once Upon A Tyne.
In the book, they candidly discuss their career as a pair, their ups and downs, highs and lows.
One chapter sees them recall bringing their BGT concerns to head honcho Simon in 2012 over lunch in California.
They recalled how Simon had gushed about the series that had just passed - but the pair weren't so happy.
In an extract from the book previously published by The Sun, the pair wrote: "We began to feel that we were wasting our time doing the auditions because all the footage of the work we were doing was ending up on the cutting-room floor...
"The experience left us feeling like we were being sidelined."
They went on to say that Simon had managed to smooth things over, and that he had trusted the two of them to come forward with any complaints.
They also opened up about their time apart - and how they came to realise that they were happiest when working closely with one another.
Ant stepped down from TV commitments - including I'm A Celebrity - in 2018 following a drink-driving conviction, with him checking into rehab to battle drink and drug addiction.
Dec explained this evening: "It was an incredibly difficult time, and for me I just wanted to fulfil our obligations. I wanted to do the TV shows and keep them going.
"When the time was right we knew we would sit down together and decide what the future was going to hold for us both."
He added: "It really was an uncertain time, both of us individually went away and thought about what the future could hold, would hold... ultimately at the end of it all we sat down together under the glare of everything.
"We were very honest with each other and we both realised what made us happiest was being together and working together."
Ant came in: "I just had to get myself right and then I did, and we spoke a lot as friends, forgetting the carer.
"We decided the best thing to do was to get happy, get well and come back when I was better, and that is what we did."
