Mark Wahlberg returns as John Bennett, while Seth MacFarlane voices Ted and performs motion capture for the character, reported Ace Showbiz.
'Ted 2' sees Ted marrying his girlfriend Tami-Lynn (Jessica Barth) and the pair deciding to have a child - but needing some help from a sperm donor.
The pair also face a legal battle as the US Government demands proof Ted is a real person and can get all the rights accorded to one.
Amada Seyfried plays lawyer Samantha Jackson, who they hire to help with the case.
