Old sci-Fi movie where alien creature comes out of woman's belly button?

[DB]

There was this scifi movie I've seen long ago that was based somewhere in the universe where there was this girl put on a table where a creature came out of her belly button (shaped like a power plug entrance) and cranked around her body then went back in the belly.
Does anybody know this movie/it's name/who stars in it?
Any help would be good. Thanks

It's aliens or alien the 80s version
Sigornie weaver stars in it I don't know how to spell her name. The aliens are called xenemorphes

Aliens & Matrix came to mind...
