Seth Macfarlane has confirmed he will not be hosting next year's Oscars.

The actor-and-comedian hosted this year's 85th Academy Awards and was asked to return in 2014 despite being criticised for his divisive humour making for a controversial show in February.

However, the 'Ted' director has taken to his Twitter account and announced he will not be returning to join this year's producers Craig Zadan and Neil Meron for a second year.

He wrote: ''Traumatized critics exhale: I'm unable to do the Oscars again

''Tried to make it work schedule-wise, but I need sleep. However, I highly recommend the job, as Zadan and Meron are two of the most talented producers in the business. My suggestion for host is Joaquin Phoenix.''

When news broke last month Seth had been offered the chance to lead next year's ceremony, he was said to be unsure whether to accept - particularly after he dedicated four months in preparation for this year's event.

The 'Family Guy' creator's controversial brand of humour - which included his ''boob song'' skit noting actresses who have appeared topless on screen - was proven a success with viewing figures up to 40.3 million viewers in the US, a three per cent increase on last year's ceremony.
