Mena Suvari is the "nerd" in her group of castmates.
The model-and-actress is best known for her roles in American Beauty and hit comedy franchise American Pie.
The 33-year-old stars in upcoming British film The Knot, which she has been busy filming in London.
"Did we have some great nights out in London? Oh yes," she told British magazine OK!
"I'm not the big partier or drinker - I'm the nerd on set - but I had the most amazing time."
The stunning actress has managed to keep her youthful looks, from the first American Pie movie in 1999.
Mena looked great when she hit the big screen in American Reunion this year, and says it's all down to her healthy lifestyle.
"I don't drink alcohol, I don't smoke," she explained.
"I'm currently doing this 'eat right for your blood type' diet. I don't know what that's all about, but I'm trying it!"
The Knot, a Bridesmaids-style wedding comedy, hits cinemas from this month.
