In perhaps a case of history repeating itself, a blonde bombshell serenaded a notoriously libidinous Democratic president last night: But this time it was Lady Gaga sending up Bill Clinton, so things wouldn't have been complete without some extra raunch and an F-bomb. Appearing at last night's "A Decade of Difference" concert in salute of the William J. Clinton Foundation, Gaga told the crowd, "Tonight I thought we'd all get caught up in a little Bill romance," later telling the former prez, "I love you and your hot wife," before demanding that "Billary" "sit back down where you belong in the Oval Office with those high heels on." Finally: "If someone had told me so many years ago that I'd be doing that right in front of you ... I would have given a good American f**k you."
