Kate Middleton & Ellen DeGeneres Cousins (VIDEO)

We thought by now we knew everything there is to know about Kate Middleton (except for, ahem, what she'll be wearing on her big day) but here's some late-breaking news: she and Ellen DeGeneres are apparently cousins.

The New England Historic Genealogical Society contacted the talk show host, explaining, "As we were doing the research, we discovered that you are related to Kate via a man named SIr Thomas Fairfax and his wife Agnes Gascoigne. You are distant cousins -- 15th -- but cousins still the same."

Ellen seemed super-excited to find out about her new family, even offering to pick up a little something at Pier 1 or Target before the wedding.
