Sideshow: Winehouse cancels part of European tour

British singer

Amy Winehouse

is canceling part of her European tour after she was booed for her addled behavior during a Saturday concert in Belgrade, Serbia. No show in Istanbul on Monday or in Athens on Wednesday, says publicity company Outside Organization. Whether she will do the rest of the 12-date tour will be "worked out as soon as possible."

Serbian media described the concert before 20,000 fans as a "disaster." Winehouse, who struggles with drugs and alcohol, was almost an hour late, stumbled onstage, and appeared unable to remember lyrics. She dropped the microphone and occasionally disappeared. Many angry fans walked out.

Still a single lady

Saturday was supposed to be 25-year-old Crystal Harris' wedding day at the Playboy mansion, but instead she spent it at Las Vegas' Wet Republic in a bikini and leopard-print coverup. She said she was right to call off the wedding to Hugh Hefner, 85.

"He is the sweetest person I've ever met in my entire life and I'll always love him." She says they speak daily, but he speaks to lots of other women, too, which was a problem. "It doesn't make sense to have so many women around but still have a marriage . . . so it was the right thing" - and it had nothing to do with her rumored romance with Dr. Phil's son Jordan McGraw, her music producer, whom she describes as "one of my really good friends."

Hefner, she says, is fine, and they will see each other Monday when she goes to the mansion to return mementos, including her ring.

'Green Lantern' shines

Ryan Reynolds is the latest superhero to rule the weekend box office.

Reynolds' Green Lantern debuted at No. 1 with $52.7 million domestically, a fair if unremarkable opening. The movie added $17 million in a handful of overseas markets where it has opened.

The previous weekend's top flick, Paramount Pictures' sci-fi adventure Super 8, slipped to No. 2 with $21.3 million. Jim Carrey's family comedy Mr. Popper's Penguins, from 20th Century Fox, came in at No. 3 with $18.2 million.
