Cowell said he will "stand by" his friend.
Britain’s Got Talent judge Simon Cowell said he will stand by Ant McPartlin and insisted he is going "to get himself back together".
The show's first pre-recorded episode airs tonight and, because the audition stages were filmed in January, sees Ant and Dec present as a duo. Scenes show a fragile Ant breaking down in tears after a magician's "emotional audition" revealed his baby daughter's cancer battle.
McPartlin will, however, not present the live shows and Declan Donnelly will go it alone as he did for the final two instalments of
Saturday Night Takeaway - after his partner was charged with drink-driving and admitted himself to rehab.
Speaking for the first time about Ant’s problems, Cowell said: "This was a very difficult one for all sorts of reasons.
"As you will see in the show, we always stand by our friends. We are all human.
"Our show of friendship is what we did in the first show if that makes sense.
"Nobody was excluded, it wasn’t awkward, but it is a very difficult time for him.
"We have known each other a long time and you stand by the people you have worked with over the years. The most important thing is he has manned up. He is going to get himself back together.
"This is what happens, it is happening to people all over the world. People, for whatever reason, get into a rut and times like this you stand by your mates. It has always been that way.
"But the show goes on, it’s a simple as that."
Asked if he would invite Ant back to the show in 2019, Cowell said: "Of course. This is what happens."
McPartlin is due to appear at Wimbledon Magistrates’ court on Monday.
