Martha Stewart Living Omnimedia has taken a 40 percent stake in WeddingWire, investing an undisclosed amount into the company.

WeddingWire is a combined listings site for services (like photography and cake-making) and organization tool. It also has social and community features, and other tools for planning and sharing information.

The deal is notable because MSLO has been expanding its presence online in a number of verticals, both through building its own properties and, increasingly, making investments in startups. The company also hired a Yahoo sales executive last year.
