Actor Alec Baldwin has paid tribute to Sybil Christopher following her death last week (ends10Mar13).

Richard Burton's first wife, who passed away at the age of 83, co-founded the Bay Street Theatre in Sag Harbor, New York, where Baldwin has appeared on stage in the past, and the 30 Rock star has fond memories of working with her.

In a post on his page, he writes, "Rest in peace Sybil Christopher, who helped found Bay Street Theatre. A joy to work for and to be around."

Christopher, who acted under the stage name Sybil Williams, married Burton when she was just 19, but the marriage ended after his infamous affair with Elizabeth Taylor on the set of the 1963 film Cleopatra.
