NEW YORK (AP) -- Christina Aguilera says that although she went to Rwanda to help others, she ended up helping herself.
The 32-year-old singer visited Rwanda in June for a hunger relief effort. She said the experience helped her ground herself.
"It came at a time in my life when I really needed to be far removed from anything to do with work or being on camera," the Grammy winner said in a recent interview. "It came at a time in my life when I needed to sort of experience what's going on with the world beyond entertainment."
Aguilera has been a spokesperson for Yum! Brands' World Hunger Relief effort since 2009, and has also traveled to Haiti and Guatemala. She said being a mother -- she has a 5-year-old son Max -- made her feel more empathetic for those suffering from hunger around the world.
"It's so sad to think there's nothing that sets any of us apart," she said. "And when you go into the field, you really see that and feel that we're all one in the same, it's just we're born under different circumstances, and it's sad and I don't understand why, but I feel what I feel and I did what I can."
On her Rwanda trip, "The Voice" mentor served food to children and visited refugee camps, which she called "one of the most difficult moments."
"They had to escape everything and everybody they knew and loved, and it's just a lot to really open yourself up and feel all that," she said, on the brink of tears. "And you just want to help out in whatever way that you can, and obviously I get emotional about it when talking about it, but I think it's important to feel those things."
Yum! Brands Inc. is the parent company to KFC, Pizza Hut and Taco Bell. The company said its World Hunger Relief effort has raised nearly $150 million for the United Nations World Food Programme and other organizations since its launch in 2007. Aguilera's PSA debuts Thursday, featuring her song "Light up the Sky."
She will return for the fifth season of NBC's "The Voice" Sept. 23.
'Suge' Knight arrested after traffic stop in Los Angeles
LOS ANGELES (AP) -- Former hip hop mogul Marion "Suge" Knight has been arrested on an outstanding warrant after being pulled over for a traffic violation in Los Angeles.
Police Officer Sara Faden says the founder of Death Row Records was stopped shortly after midnight Wednesday near Beverly Hills. She declined to say what the alleged traffic violation was.
Officers determined Knight was wanted on a misdemeanor warrant and police took him into custody. Records show he was booked into county jail and released several hours later on $20,000 bail.
A warrant was issued for Knight's arrest in February after he skipped a court appearance for driving without a license.
Death Row Records helped make stars of rappers such as Dr. Dre, Snoop Dogg and Tupac Shakur.
Knight filed for bankruptcy in 2006.
'Star Wars' actor Mayhew has surgery on knee
FORT WORTH, Texas (AP) -- Actor Peter Mayhew, who portrayed towering Chewbacca in the "Star Wars" films, has had double knee-replacement surgery at a Texas hospital.
Mayhew was recovering Wednesday at Plaza Medical Center in Fort Worth. Angie Mayhew says her 69-year-old husband had the surgery Monday and hopes to walk again. She says her spouse has been using a wheelchair for two years.

The Mayhews live in Boyd, about 20 miles northwest of Fort Worth.
