For the second straight evening, Paris Hilton and Benji Madden took in the Vegas nightlife - this time in celebration of Allison Melnick’s birthday on Saturday night.

Joining the former Simple Life star and her Good Charlotte rocker boyfriend at Tao nightclub were Paris' sister Nicky and her beau David Katzenberg - with the group mixing it up with a little drinking, dancing and socializing.

As previously reported by Gossip Girls, Ms Hilton spent the prior evening filming her new MTV reality show, Paris Hilton's My New BFF, at the same popular Sin City nightspot.

During her Friday night festivities, Paris was greeted with her song "Stars Are Blind" before continuing to dance, smoke cigarettes and drink Grey Goose vodka, dashing rumors that she was expecting her first baby.

Getting herself ready for a day behind the cameras, Kim Kardashian treated herself to a manicure and pedicure at a Beverly Hills spa.

The reality starlet and her family are lined up to make an appearance on an episode of Celebrity Family Feud, being filmed today (Kim's broadcasting video from the set live to her blog today).

Meanwhile, the "Keeping Up with the Kardashian's" hottie and her sisters Khloe and Kourtney are auctioning a lunch date and shopping on eBay for charity, with a portion of the proceeds to be donated to the Dream Foundation, an organization that grants wishes to terminally-ill adults.

Of the auction, Kim says on her eBay page:

"My sisters Khloe and Kourtney and I want to have lunch with you! We can talk about what it is like being in the public eye, having your own reality show, girl talk, and of course our favorite topic - fashion!"

"Not sure where we will meet for lunch, but it will be somewhere nice not too far from our store DASH, about 45 minutes away from Beverly Hills and Hollywood. After lunch, let's all go back to DASH and do some shopping! We want to help you look your best and will give you a $500 gift certificate to start out with. We all have different styles and tastes so you can be sure to get some helpful advice."

In typical fashion, Amy Winehouse popped out of her London pad on Saturday night to chat it up with anyone and everyone who decided to drop by.

The Rehab singer first opened her door to speak with journalists following further damaging allegations in the Sunday papers.

According to British tabloid reports, Winehouse is said to have appeared in a video, shot in 2007 by her incarcerated husband Blake Fielder-Civil, singing a racist song.

Sucking on a lollipop as she spoke, Amy told the assembled media that she was "very sorry if any of her words had been misunderstood or caused offense."

Later on the same night, the troubled crooner once again was in her open doorway - greeting a friend dressed as Jimi Hendrix who wandered up to her front door.

Making one final appearance, Amy was seen peering out of her window as fans serenaded her from the street in the early hours of the morning.

Wearing an all black, full length summer dress and flat flip-flops, Gwen Stefani paid a visit to her parents house in Orange County.

The Hollaback Girl singer was there to drop her young son Kingston off for babysitting time with the grandparents, while also stopping in for a change of clothes.

After swapping outfits and chatting with her folks, Gwen made her way outside with Kingston being taken for a stroll by his grandfather, Dennis Stefani.

Decked out in a fashionable print strapless maxi with five inch heels, Gwen hopped into her ride - heading off to a Saturday evening party in Bel Air.
