Heidi Montag and Spencer Pratt's Casual Halloween

Keeping things surprisingly low-key, Heidi Montag and Spencer Pratt enjoyed a casual, costume-free Halloween outing on Saturday (October 31).

The "Hills" co-star couple kicked things off with a relaxing lunch in Beverly Hills, with the twosome chatting away on an outdoor patio.

Feeling refreshed after their Halloween lunch, the MTV reality stars continued along - making their own little auto-biographical film on a handheld video camera.

Amidst their travels, Heidi and Spencer also fit in a bout of shopping - loading up with a few items before heading back to the homefront.
