Perennial problem child Courtney Love was arrested yesterday at London's Heathrow Airport on charges of abusive behavior and endangering an aircraft during her flight from Los Angeles, according to an airline spokesman. "She was having a row with one of the flight attendants," one passenger told reporters. British police said Love, apparently en route to an Elton John charity show today, had refused to sit down and buckle her seat belt, prompting the plane's captain to radio ahead. Officers were waiting to arrest the 38-year-old singer-actress when the plane landed. Detained for several hours, she was released with a warning, according to a Love spokesman. . . . Party's Over: Universal Music Group has canceled its post-Grammy Awards gala, a move variously attributed to budgetary concerns and fears of violence between rivals in the hip-hop scene. Universal declined comment, but the Los Angeles Times reported yesterday that the party was scrapped in part because the company was worried a feud between Brooklyn rapper 50 Cent and Murder Inc. chief Irv Gotti might erupt into violence at the gala. Meanwhile, the release date for 50 Cent's new album, "Get Rich or Die Tryin'," has been pushed up from Feb. 11 to tomorrow -- reportedly because of the bootleg copies of the disc already in wide circulation . . . Back in Action: Soul singer Anita Baker is back on the music scene after taking an eight-year break to be a full-time mom and to care for her own mother, who had Alzheimer's disease. Among her tentative first steps back into live performance, Baker has scheduled a couple of shows in the area: May 23 and 24 at Wolf Trap. No recording plans have yet been announced.
