Alyson joins American Pie reunion
Alyson Hannigan has signed up to join American Pie: The Reunion.
The Buffy The Vampire Slayer star's commitment to the sequel had left a question mark over the project as the story centres on her marriage and child with Jason Biggs' character.
But Deadline.com reports Alison has agreed to shoot her part in the film before she returns to CBS sitcom How I Met Your Mother.
Jason, Seann William Scott and Eugene Levy are already signed to reprise their roles in the forthcoming fourth instalment, while Thomas Ian Nicholas, Tara Reid, Chris Klein, Mena Suvari and Jennifer Coolidge are reportedly in talks to appear.
Harold & Kumar: Escape From Guantanamo Bay's Jon Hurwitz and Hayden Schlossberg are writing and directing Reunion, which is due to begin filming in May.
The original 1999 film and its two sequels were box office hits and spawned a new genre of raunchy teen comedies, but the following spin-offs - Band Camp, The Naked Mile, Beta House and The Book Of Love - were straight-to-DVD releases.
