But whilst Ant continues to stay out of the limelight to help him recover from his addictions, ITV's chief executive Carolyn McCall has confirmed the Geordie star will return to his presenting roles when he is ready.
Carolyn told ITV News, "So, we wish Ant well. Clearly he won't come back a moment too soon.
"So I mean, he will come back when he's well and when he is ready to come back, and ITV will not be putting him under any pressure to come back unless he's well and fit enough to come back."
The statement read, "Ant has decided to go back into treatment and step down from his current TV commitments. He has spoken with Dec and ITV today and asked for time off for the foreseeable future."
Ant's best friend and co-presenter Dec Donnelly then done a grand job of hosting the final two episodes of Ant & Dec's Saturday Night Takeaway, as well as the Britain's Got Talent live shows.

Despite ITV's chief executive Carolyn McCall confirming that Ant will return, it's not understood when, although fans will be hoping he's back in time for the brand new series of I'm a Celebrity...Get Me Out of Here! later in the year.
Speaking to Best Magazine, Stephen said, “Fingers crossed, Ant will get the treatment he needs and be back to his old self for next year.
"But he does need the rest and to be left alone, and given the time to recover."
