Hollywood Headlines: a crazy week in review

The “Two and a Half Men” actor continued his manic media blitz with interviews on major networks including ABC, NBC and CNN and various radio outlets. We’ve learned that the haggard-looking actor is indeed on a drug: It’s called Charlie Sheen. The bizarre escapades and revelations about his live-in goddesses prompted estranged ex-wife Brooke Mueller to serve him with a restraining order and take away his twin sons. But don’t feel so bad for the tiger-blooded actor with Adonis DNA. Sheen also joinedTwitter this week and has already accumulated 1.6 million followers. Boom!  (ABC News / Associated Press)

The announcement of the celebrity cast for the highly anticipated new season was teased during Sunday’s Oscar telecast, but the stars were revealed Monday and they include former Jenny Craig spokeswoman Kirstie Alley, Hugh Hefner’s ex-girlfriend Kendra Wilkinson, talk-show host Wendy Williams, all pictured above, and original “Karate Kid” Ralph Macchio. ABC continued to drag out the announcements by waiting until the next day to reveal the stars’ dance partners.  (Kirk McKoy / Los Angeles Times; Alberto E.

Christina Aguilera and boyfriend Matt Rutler were arrested early Tuesday on suspicion of being publicly intoxicated and driving under the influence, respectively. She was released a few hours later and will not be facing criminal charges. And by Thursday, it was revealed that the “Burlesque” singer/actress would serve time, but as a mentor for NBC‘s newest talent show “The Voice.” That’s one of the quickest comebacks we’ve seen in a while, but hey, at least Pink’s glad she’s not as sloppy as her cohort.   (Matt Sayles / Associated Press)

John Galliano, the noted British fashion designer, was fired by the French fashion house Christian Dior over alleged anti-Semitic comments he made in a Parisian cafe. He was caught on video saying he “loved Hitler” and will face trial in France over the remarks. Oscar-winner Natalie Portman, who is the face of the Miss Dior Cherie fragrance, railed against the designer and said she would no longer be associated with him over his remarks. Speculation about whether he would show at Dior’s Fashion Week show circulated among fashionistas, but the show went on without its designer anyway. His own namesake brand was set for Sunday, though it will appear in a much more informal setting. Galliano, who has since checked himself into rehab, had acquired an unlikely ally in Whoopi Goldberg.  (Ian Langsdon / Getty Images)

Reality TV star Kim Kardashion debuted her new single, which she created with producer The-Dream, on “On-Air with Ryan Seacrest” Wednesday. The radio show host loved the auto-tuned track on which Kardashian sounded bored despite the upbeat music paired with her sleepy vocals.   (Dan Steinberg / Associated Press)

The 90-year-old actor gave an emotional address to the Senate Special Committee on Aging Wednesdays about the elder abuse he says he experienced at the hands of his stepson and urged Congress to take action on the greater issue.  (Alex Brandon / Associated Press)

The 94-year-old actress was rushed back to the hospital Thursday due to blood-flow problems in her left leg. The one-time socialite was to be released from the hospital again Friday after declining doctors’ recommendation that she have surgery to amputate her remaining leg. Her husband, Prince Frederic Von Anhalt, said she is on medication and without surgery has “a 50-50 chance” of surviving for another year.  (Curt Wilcott / Associated Press)

“American Idol” is still America’s favorite show, leading in ratings despite naysayers expecting it to crash and burn this season because of its new format and new judges. Though the singing show has continued to decline in the ratings 24.4 million viewers, down 7% compared with last season, according to the Nielsen Co., and it may have judge Steven Tyler to thank for that. This week the mens’ and ladies’ nights whittled down the competition to the top 13, pictured above, who are soaking up the spotlight.  (Chris Pizzello / Associated Press)

After Justin Bieber and Selena Gomez stepped out as a couple at the Vanity Fair party on Oscar night, the pair went on to celebrate the pop star’s 17th birthday a few days later, but not without a scuffle with a paparazzo. The in-demand singer’s hair also fetched $40,668 at auction. The EBay bidder was an online casino, sadly, not an obsessed fan that may or may not have punched Gomez.  (Carlo Allegri / Associated Press)

It should have been an exciting week for “Black Swan” star Natalie Portman. But after winning the lead actress Oscar, the starlet has made headlines for speaking out against John Galliano and has become the target of Fox News’ Mike Huckabee. Huckabee, the possible GOP presidential aspirant, who’s been out promoting a new book, misspoke regarding President Obama’s origins and attacked Portman, who is currently engaged, for setting a bad example for getting pregnant before getting married.   (Larry A.
