Me and Gwennie’s like bacon & eggs…

Gwen Stefani and Gavin Rossdale went to a Halloween party… She was an egg, he was bacon…

Very odd that there’s also pictures of Katy Perry in an egg costume at another, completely unrelated, event.  I’ve never heard of anyone going as an egg… and now 2 celebrities in one Halloween weekend?  Is this like a new trend in Halloween costumes?
