Recently rehabbed Amy Winehouse is back onstage, but during the inaugural show of her 17-date tour, the bee-hived belter lost it — slurring her speech, threatening the audience and knocking into equipment. After appearing on stage 30 minutes late, the rehab-averse singer dedicated several songs to her recently incarcerated husband, Blake Fielder-Civil. When the audience tired of her constant references to Fielder-Civil (she changed “baby” to “Blakey” in some songs), Winehouse then addressed the audience as “monkey c*nts” and said, “Just wait till my husband gets out of incarceration. And I mean that.” Reviews from the show state that Winehouse forgot several lyrics to her songs and spent much of the time crying. British tabloid The Sun has the disastrous footage of the U.K.’s Britney Spears.
