Heidi & Spencer's Halloween Fun

It’s “Speidi“! Get it? Yuk yuk! Yuk yuk!

The Hills star Heidi Montag and fiance Spencer Pratt make their way to a friend’s Halloween party near Santa Monica on Sunday, dressed in full costume.

Heidi went as a semi-conservative mermaid (where’s the bikini top?!), while Spencer wore a Spider-Man outfit. (Um, hello there.)

When asked whose party they were going to, the couple jokingly replied, “Britney Spears“.

Happy Heidi-ween, everyone!
