category.php normal posts & custom post type related posts.

Hi all,

I’m working on our corporate website and having the following problem:

Due to our weekly blog, I’m combining normal and custom post types with basic categories. When viewing a category, i’d like to show this:

1) Category name .. done ..
2) Category description .. done ..
3) Portfolio posts (custom post type!)
4) Blog posts (normal posts)

Does anyone know how to get CTP posts related to a category?

Kind regards,
