The 42-year-old TV presenter retweeted a message from a fan account for American business mogul Warren Buffett, which read: "Let go of: 1 ego 2 entitlement 3 resentment 4 hate 5 doubt. Hold on to: 1 hope 2 gratitude 3 optimism 4 curiosity 5 love."

While the account is shared with his presenting partner Ant McPartlin, Dec has exclusively been using it while Ant takes a break from his professional duties following a tumultuous year in which he split from his wife Lisa, spent time in rehab and was fined £86,000 for drink-driving.

Following the drama, Dec was forced to present the final two episode of this year's 'Ant & Dec's Saturday Night Takeaway' series and all of this year's 'Britain's Got Talent' live shows on his own.

And he is set to be joined by Holly Willoughby for 'I'm A Celebrity... Get Me Out Of Here!' as Ant continues to take time out of the spotlight.

A source recently said: "Holly is 100 per cent confirmed to be going into the Jungle this year as Ant's stand-in.

"It's been in the works for weeks as ITV were really keen on getting her in.

"They've taken their time announcing it as they wanted to be sure Holly could fit it in with her family and other work commitments."

Holly, 37, is a close pal of Ant and Dec, both 42, and Donnelly is believed to have suggested her to ITV chiefs to replace Ant.

The insider explained: "Dec first brought up Holly last year, after Ant went into rehab the first time.

"Dec would have had a say in it because the most important aspect of the show is the chemistry between the hosts.

"Ant and Dec have this natural back-and-forth and bosses didn't want to just replicate that.

"They wanted someone who could bring their own energy to the screen."

And Ant will return to ITV "when he is ready", according to the broadcaster's chief executive.

Carolyn McCall explained: "He will come back when he's well and when he is ready to come back.

"ITV will not be putting him under any pressure to come back unless he's well and fit enough to come back."

Asked specifically whether he'll be returning to ITV, she replied: "As far as I know, that is true."
