Rihanna looks lovely as she poses for photographers at the 2008 UNICEF Snowflake Lighting at Grand Army Plaza in New York City today.

Rihanna has partnered with UNICEF’s fight to save children worldwide and reduce the number of children dying from preventable causes from 25,000 to zero. It’s an organization that has saved more children’s lives than any other humanitarian organization.

Says Caryl Stern, President and Chief Executive Officer of the U.S. Fund for UNICEF:

“We are thrilled to have Rihanna take part in the lighting ceremony in New York City. She has tremendous enthusiasm for helping those in need and is the ideal person for spreading the UNICEF Snowflake’s message of hope, peace, and compassion for children around the world.”

Rihanna flipped the switch to illuminate the magnificent UNICEF Snowflake, which acknowledges the beginning of the gift-giving season across the world. The celebration included treating the crowd to a live performance by Ne-Yo!

Nicole Richie appeared with a group of celebs at the Alberta Ferretti Store grand opening yesterday in Los Angeles.

She and her boyfriend Joel Madden also attended H&M’s Divided Exclusive Collection Launch Party on Tuesday in West Hollywood.

The U.S. Fund for UNICEF just announced that Joel Madden, who is a UNICEF Ambassador, and Nicole Richie will be hosting UNICEF’s 2008 Beverly Hills Snowflake Lighting ceremony on Saturday, November 22. Joel and Nicole recently launched the Richie-Madden Children’s Foundation, a charity which provides funds and assistance to groups focused on improving pediatric health, education and human rights, in the U.S as well as overseas.

Rihanna took to the stage at the “Justin Timberlake And Friends Concert” at Planet Hollywood on Friday in Las Vegas. She sang Umbrella and Disturbia at the charity show. Some of the other celebrities who lent their time and talent were: The Jonas Brothers, Will.i.am, Adam Levine (of Maroon 5), 50 Cent, Boyz II Men, Esmee Denters (from J.T.’s label), and Leona Lewis.

She is wearing a gold-plated Alanna Bess cuff with black triangle details. I think she looks like a bumble bee, but then her sense of style and fashion is all her own.

“Hi Everyone,

This past year, philanthropy has opened my eyes to so much need and so much beauty. I have also realized how easy it is to help, and how rewarding it feels to be able to make a positive difference in someone’s life.

Last week, my friend Carlos and I brought a video camera to Beyond Shelter. Just the two of us. There are 175 children with families here, most of whom have been homeless at some point.

Today, they play in a concrete courtyard. Because of the neighborhood they live in, they have nowhere else to play. I met a woman who has ten children living in a three-bedroom apartment. The Beyond Shelter rec room only allows ten kids at a time. I wish you could all go there with me and see.

I’d like to share with you a glimpse of these beautiful children through my eyes.

Please watch this video, Text “CHILD” to “90999” up to 5 times, share this with as many people as you can — and ask them, from your heart, to join you in bringing more light and laughter to these beautiful faces.

It’s just you and me making this happen. There is so much we can do together to help. A playground is just the beginning. We can change the world — you and I.

I’m asking from my heart, and I cannot do it without your help. Please, you guys. Thank you for watching, texting and passing it on.

Peace & and love,

Nicole”

While she seems to have grown up a lot since the birth of her child, something tells me that the cost of one of her designer dresses or purses would cover the cost of the playground for these kids!

Britney, her father Jamie and manager Larry Rudolph were at the Polo in the Palisades event at the Will Rogers Polo Club in LA this past Saturday afternoon.

They were cheering on a team of players wearing pink polo shirts with “Spears Family” written on the back. She was the guest of honor at a charity match. It was sponsored by the Promises Foundation - an LA-based charity which helps Miriam’s House, a home for recovering mothers and their children.

Here she is posing with fellow guest Blair Berk, a criminal defence attorney.

Tomorrow, Brit’s latest single “Womanizer” is dropping on the Z100 and KIIS-FM radio stations.

Get excited, the B is back.

JLo competed in the Nautica Malibu Triathlon today. She actually completed the half mile swim, 18 mile bike ride and 4 mile run. Her time was 2 hours, 23 minutes and 28 seconds. Go JLo! I’m impressed since she had called in sick after she had injured her foot and was unable to make it as a final guest judge on “Project Runway.” Well she rested up and worked her booty off all in the name of raising money for charity.

Jennifer told the crowd after she crossed the finish line:

“I feel really great and so glad I finished and that I made it out of the water but more amazing than that, I feel really great that we raised $127,000 for the Children’s Hospital of Los Angeles and hopefully it’ll go to good use.”

Actor Matthew McConaughey also competed in the triathlon. He time was 1 hour, 30 minutes and 44.7 seconds.

Paris Hilton’s grandpa is donating 97% of 2.3 billion dollar foturne to the Conrad N. Hilton Foundation. This foundation was named after the first Hilton that founded it in 1919.

Barron Hilton has left his kids and grandkids with a measly $69 million to split and remember there is taxes on their inheritance!

Although I am sure Paris Hilton will be fine, because of all the money she is raking in now, and all the money her families hotels currently make, I am sure she is a pit pissed by what her grandpa is up to. I on the other hand think it is wonderful!
