REUNITED: The on-again, off-again couple of TLC singer Lisa “Left-Eye” Lopes, 30, and former Atlanta Falcons wide receiver Andre Rison, 34, are once again back together and are planning to get married. (In 1994, she was arrested for torching his house, which they were sharing at the time.) “There’s definitely been a lot of growth on both our parts,” she says in the September issue of Jane magazine . . . GONE: Two all-star shows honoring Michael Jackson sold out five hours after tickets went on sale this week — despite ticket prices that ranged from $45 to $2,500. Former Guns N’ Roses guitarist Slash has been added to the all-star lineup of the Sept. 7 and 10 performances at New York’s Madison Square Garden . . . DIED: Master science fiction writer Poul Anderson, 74, author of “Genesis,” “Tau Zero” and other commercial and critical successes, died Tuesday at his northern California home of complications related to prostate cancer. He was a former president of the Science Fiction and Fantasy Writers of America and a winner of three Nebula Awards and seven Hugo Awards . . . DISMISSED: “Disturbing the peace in a thoroughly thoughtless manner” charges against Austrian actor Hubert “Hubsi” Kramar, who allegedly arrived at a Vienna society ball last year dressed as the late fascist dictator Adolf Hitler, have been dropped. A small claims court reportedly upheld Kramar’s argument that he was satirizing the presence of current Austrian Prime Minister Joerg Haider’s far-right Freedom Party.
