Ellen DeGeneres and Portia de Rossi celebrated their fourth wedding anniversarySaturday with dozens of their closest friends.

The couple, who wed in 2008 during the time same sex marriages were legal in California, threw a casual BBQ at a ranch near Santa Barbara.

Several of the couple's famous friends attended. Katie Perry came without new boyfriend John Mayer. Gwen Stefani and Michelle Williams were also spotted.
