Wahlberg: 'Family Guy' director has started on 'sick' sequel to 'Ted'

Mark Wahlberg says 'Ted 2' will be "sick".

The 'Ted' star revealed director Seth MacFarlane has begun work on a sequel to this year's hit R-rated comedy caper about a teddy bear that comes alive, although film studio Universal Pictures has yet to officially confirm the news.

Speaking to Collider.com, he said: "They are working on it now. The great thing about it is Seth's ideas for the second one are sick."

The 41-year-old actor also praised 'Family Guy' creator Seth for bringing fresh ideas to the proposed sequel because of his success in TV.

Mark explained: "He comes from a world of television so he knows how to tell stories, the way that most people don't. He's a different kind of guy."

'Ted' - which also stars Mila Kunis and Giovanni Ribisi - proved to be a smash success earlier this year, grossing more than $500 million worldwide.

The 'Broken City' star is set to begin work on 'Transformers 4' - which he recently called the "most important" role of his life - after hitting it off with director Michael Bay while filming 'Pain & Gain'.

He said: "We had such a great time working together. We kind of complement each other throughout the entire process - what he does and what I do, and how we were able to do it together.

"After that I said, 'Dude, we have to work together again', and he said, 'I have a project you might be interested in'. That's how 'Transformers' came about."
