Carey fans rejoice, Dumb And Dumber 2 has been confirmed to shoot this September.

Plans for a follow-up to the hit 1994 comedy have been off and on for years but now the project has finally been green lighted.

Charting the cross-country adventures of two far from bright friends, co-director Peter Farrelly insisted the new film will be the first true sequel.

Farelly told ComingSoon.net: 'We're getting set to shoot Dumb And Dumber 2 in September. It's the first sequel we’ve ever done and we've got Jim Carrey and Jeff Daniels back.'

Farrelly was referring to  the 2003 prequel Dumb And Dumberer: When Harry Met Lloyd, but that version did not feature the original stars. 'We did not do Dumb And Dumberer. That was a studio thing,' Farrelly added.

'So we've always wanted to do a sequel and Jim called up. Jeff always wanted to do it. We always wanted to do it. Jim was busy, but he called and said, 'We've got to do this thing again'. He had just watched Dumb And Dumber and he said, 'This is the perfect sequel. Let's do it.'

Farrelly will co-direct with his brother Bob.

Here's the trailer for the 2003 "Dumb and Dumber":
