Streisand was one of the big-name guests slated to appear at a Jerusalem convention hosted by Israeli President Shimon Peres beginning May 13.
The American diva was supposed to perform a rendition of the Hebrew prayer Avinu Malkeinu, or "Our Father Our King." But Peres' office said Tuesday that Streisand has now announced she will not be coming. It says she gave no reason for the sudden cancellation.
