Piers Morgan has admitted his US chat show has "all been trial and error thus far".

The former newspaper editor - who took over from talkshow legend Larry King in January - has scored high profile interviews with stars like Charlie Sheen and Oprah Winfrey.

But he acknowledged the programme had its faults, telling the Hollywood Reporter: "I like the errors more than the successes.

"The successes are pleasing for a few seconds and then you move on. It's when things don't work out quite how you thought that are very interesting."

But Piers - who also appears alongside Sharon Osbourne on the judging panel of America's Got Talent - said he didn't mind blowing his own trumpet.

"Everyone in this business is a self-promoter; I just pride myself on being better at it than most of them," he added.
