Vince Vaughn is signed up to join Will Ferrell on new film Daddy's Home.
The Frat Pack heavyweights - who have previously worked together on comedy hits including Anchorman and Old School - will team up once again for the Paramount film, reports Variety.
The story for Daddy's Home is about a mild-mannered radio exec, played by Will, whose life spirals out of control when his wife's ex-husband (Vince) comes back into her life.
Will's character is forced to compete for his stepkids' affection with their real dad.
Blades of Glory star Will, 45, is also involved in producing Daddy's Home, which will be directed by scriptwriter Etan Cohen, whose previous work includes Men In Black 3 and Tropic Thunder.
Apparently Vince, 43, will shoot Daddy's Home before starting work on the film Business Trip which he signed up to last month.
Vince is in two films this year, The Internship about a washed up salesman who gets work experience at Google, and Delivery Man, about a sperm donor who finds out years later that he has fathered hundreds of children.
Will also appears in The Internship and is currently filming Anchorman: The Legend Continues, as well as voicing a part in The Lego Movie.
He has a TV mini series out this year, The Spoils of Babylon, which he stars in with Tobey Maguire, Hayley Joel Osment and Kristen Wiig.
