ZSA ZSA GABOR: Zsa Zsa Gabor's publicist says the Hungarian-born actress was taken to California's Ronald Reagan UCLA Medical Center because of poor circulation in her leg.
Gabor's representative, John Blanchette, told CBS Radio the 94-year-old actress was hospitalized Wednesday because she had "no blood flow" to her left leg.
Most of her right leg was amputated Jan. 14 to treat a blood clot and prevent infection.
Gabor has been in and out of the hospital since July after falling out of bed at her home and sustaining an injury that required a hip replacement.
JOHN GALLIANO: Celebrity fashion designer John Galliano has left Paris and is seeking help at a U.S. rehab for his alcohol addiction, The New York Times said.
The French fashion house Christian Dior fired Galliano this week after a video surfaced online allegedly showing the British designer making anti-Semitic remarks while drunk in a Paris bar.
The Times said Galliano is believed to be heading to The Meadows, the treatment center in Wickenberg, Ariz., where singer Elton John and fashion designer Donatella Versace were treated for their substance-abuse problems.
Natalie Portman, the Israeli-born actress who won the Best Actress Oscar Sunday for her work in "Black Swan," also is the face of Miss Dior Cherie perfume. She said Tuesday she is "deeply shocked and disgusted by the video" and will never work with Galliano again.
MICKEY ROONEY: Nonagenarian actor Mickey Rooney called upon the Senate Special Committee on Aging in Washington to help end the abuse of elders by their caregivers.
Rooney, 90, has obtained a restraining order against his stepson and stepdaughter, claiming they emotionally abused him for years and took over his finances.
"You can't believe that it's happening to you," CNN Wednesday quoted Rooney as telling the committee. "You feel overwhelmed."
During the hearing, Rooney suggested Congress pass a law to make the abuse of seniors at the hands of family members and caregivers a specific crime.
"I'm asking you to stop this elderly abuse. I mean to stop it. Now. Not tomorrow, not next month, but now," he said.
Rooney's film credits include "Boys Town," "Babes in Arms," the Andy Hardy film series, "Breakfast at Tiffany's" and "Night at the Museum."
He received a special Academy Award in 1938 and an honorary award in 1982, and was nominated for five acting Oscars.
A five-time Emmy nominee, Rooney won the television prize in 1982 for his performance in "Bill," as a mentally challenged man making his way into the world for the first time.
CHRISTINA AGUILERA: Grammy Award-winning singer, songwriter and actress Christina Aguilera will be a musician coach on the U.S. competition series, "The Voice," NBC said.
Aguilera joins previously announced musician coaches Cee Lo Green and Adam Levine on the show, which is to premiere April 26.
"Christina has a once-in-a-generation talent -- her voice is phenomenally distinctive and instantly recognizable," Paul Telegdy, executive vice president of alternative programming for NBC and Universal Media Studios, said in a statement Wednesday. "Her journey as an artist, who started so young in the music business, will be an inspiration to the talent she coaches on the show."
"I am so excited to be part of such a wonderful project that celebrates music and the talent behind it," added Aguilera. "To be given the opportunity to help shape new artists' careers and mentor them to see their dreams come to fruition is a task I welcome with open arms. I am so happy to be working with fellow Grammy Award-winners Adam and Cee Lo as I feel there is so much we can all bring to 'The Voice.'"
Aguilera was arrested for alleged public intoxication early Tuesday in West Hollywood, Calif.
She reportedly was arrested alongside her boyfriend, Matthew Rutler, who was charged with driving under the influence after police said they saw him driving erratically.
Aguilera's divorce and hard-partying ways have made headlines in recent months. She also was criticized for getting the words wrong when she sang "The Star-Spangled Banner" at the Super Bowl in February.
