Bullock bows out ...
LOS ANGELES (AP) -- Sandra Bullock canceled her appearance at the London premiere of "The Blind Side" days after Internet reports alleged she was having trouble in her marriage and that she had left the couple's Southern California home.
Calls and e-mails to representatives for Bullock and her husband, celebrity motorcycle builder Jesse James, weren't immediately answered.
People.com said Bullock had left the couple's home just days before a report of infidelity by her husband surfaced.
The couple were last seen together publicly at the Oscars. While Bullock didn't specifically thank James in her acceptance speech for best actress, they walked hand-in-hand on the red carpet, and he attended numerous award shows with her leading up to the Oscars.
The 45-year-old actress said Wednesday in a statement by Warner Bros. UK that she cannot attend next Tuesday's premiere of "The Blind Side" for "unforeseen personal reasons." She canceled her appearance almost two weeks after winning the Oscar for her performance in the movie.
Bullock went on to apologize for canceling her commitment and to thank people for their support of the film, which has made nearly $253 million domestically.
She and James were married in July 2005.
Osmonds cancel shows ...
LAS VEGAS (AP) -- Donny and Marie Osmond are canceling their shows this week at the Flamingo Las Vegas hotel while she copes with the death of her son.
Marie Osmond's publicist Alan Nierob said Wednesday that it's been a difficult time for the Osmonds, and the performer felt like she needed to spend more time with her family.
The Osmonds returned to the stage March 9 after funeral services for 18-year-old Michael Bryan.
Los Angeles police have said Bryan died Feb. 26 of an apparent suicide after jumping from the eighth floor of an apartment building. Autopsy and toxicology results are pending.
Nierob says the Osmonds will miss five shows before the Donny & Marie show resumes performances March 23. The show is dark Sundays and Mondays.
Amanpour to ABC ...
NEW YORK (AP) -- CNN's Christiane Amanpour is ABC's choice to replace George Stephanopoulos as host of its Sunday morning political talk show "This Week."
ABC announced the hiring Thursday in an e-mail to its staff.
It's not clear whether Amanpour's hiring signals a change in direction for "This Week," a show that's heavy on politics and domestic policy. Amanpour is best known for her reporting from war zones at CNN. She has lately been host of a daily show on CNN's International network; highlights are run Sunday on the domestic channel.
Stephanopoulos left the show in December to take over as co-host of "Good Morning America."
Amanpour will start in August, with Jake Tapper filling in until then.
