American Pie cast reunite in Oz

Tara Reid, Mena Suvari and the rest of the American Pie gang have reunited Down Under.

Mayhem broke out as the cast, including Jason Biggs, Chris Klein, Seann William Scott and Eugene Levy attended a question and answer session before the American Reunion premiere in Melbourne.

An energetic Seann, who plays Stifler, lived up to his raucous alter-ego as he "borrowed" a camera from photographers and couldn't resist a laugh after being mooned by a cheeky fan, reported the Australian Courier Mail.

Tara, who reprises her role as Vicky Latham, looked elegant in a silver one-shouldered dress, while co-star Mena (Heather) looked like a 50s-style belle in a monochrome checked dress with red heels.

Jason, who attended the event with wife Jenny, joined the cast as they sat through the fourth instalment of the hit series, and they were given a standing ovation at the end of the film.

The castmates, with the notable exceptions of Alyson Hannigan, Thomas Ian Nicholas and Eddie Kaye Thomas, had previously bonded over pies at the iconic Harry's Cafe de Wheels pie restaurant in Sydney.
