'Cosby' kid Keisha Knight-Pulliam weds ex-NFL player Ed Hartwell

Here's today's sign that you're old.

Keisha Knight Pulliam who played the youngest Huxtable, Rudy, on The Cosby Show, is a married woman.

The actress and Spelman College grad, 36, revealed Friday on her podcast, Kandidly Keshia, that she married former NFL player Ed Hardwell in a surprise New Year's Eve ceremony. Fans and celeb watchers thought they'd merely gotten engaged that night.

She also reintroduced herself as Mrs. Hartwell on Instagram Friday.

She dropped a few details on her podcast: "We did it literally in our living room in our home. We come from large family. I'm one of four, Ed is one of six. We invited people. They had no clue they were coming to a wedding. They thought they were coming to a New Year's party."
