Getting a short break from filming her new movie "Labor Pains", Lindsay Lohan was out gallivanting around the city - shopping and dining out with gal pal Samantha Ronson on Saturday (June 28).

During their journey, Lindsay and Sam were spotted at Barney's New York in Beverly Hills - buying up a few items before exiting the store with huge smiles on their faces.

Meanwhile, on the family front, life as a Lohan is getting more and more complicated by the minute - as Lindsay is waiting to find out if she has a long lost half-sister.

A woman named Kristi Horn recently claimed that she had a daughter by LiLo's dad, Michael Lohan, 13 years ago.

Addressing the issue at Hollywood's Ritual Supper Club, Michael said: "Why would someone without taking a test put something out there like this? What if it's negative? What is that going to do to her own child and my children? Is this for the fame? There was correspondence where she said Ashley, her daughter, wants to be an actress, and she's so talented."

Asked if he's spoken with his children about the matter, papa Lohan tells: "I haven't spoke to them. I'm not going to do it over the phone."

Just because she’s rich and famous, it doesn’t mean Hilary Duff is wasteful. And following a recent meal out, the “Lizzie Maguire” cutie was spotted taking her leftovers home with her.

Joined by her mother Susan, the “So Yesterday” singer was spotted leaving Toluca Lake, California hot spot Mo’s restaurant after a casual Sunday afternoon lunch.

And she looked sizzling in a strapless gold and pink printed floor-length sundress along with toe-strap sandals and a pair of sunglasses holding her hair back.

Next up on the agenda for Miss Duff - a new comedy titled “Stay Cool.” She’ll be working as part of an ensemble cast including Winona Ryder, Chevy Chase, and Sean Astin.

Moving forward with her reality show obligations, Paris Hilton, along with sister Nicky, enjoyed a day of shopping in Hollywood with the winners of a competition from "My New BFF".

The heiress sisters headed over to Robertson Boulevard after dining at The Ivy in Los Angeles - visiting Paige Denim before leaving with several bags of goodies as Paris exclaimed, "I love this!" to her handbag designer sister.

From there, the Hilton gals visited Kitson, with Nicky looking quite bored while browsing the racks as Paris had a small meet and greet with two of her adoring fans.

The former Simple Life starlet read excerpts from her new book "The Heiress Journal" while her audience of two looked on in awe - with Paris loving the attention as she continued on with her posing spree even after she was finished with the meet and greet.

Just arriving back in Los Angeles from Salt Lake City yesterday afternoon, Ashley Tisdale was spotted out for some much-needed pampering on what was her first full day back in town.

Accompanied by her mother Lisa, the Disney cutie headed on over to the Neil George Salon in Beverly Hills early Sunday morning (June 29) - leaving almost three hours later with a brand-new straightened hairdo.

As previously reported by Gossip Girls, Miss Tisdale recently wrapped up the filming of "High School Musical 3", which picks up with “High school seniors Troy and Gabriella struggling with the idea of being separated from one another as college approaches. Along with the rest of the Wildcats, they stage a spring musical to address their experiences, hopes and fears about their future.”

And now that HSM is behind her, the soon-to-be 23-year-old is also readying for the February 13th release of her first lead role in “They Came From Upstairs”.

Enjoying time away from the field with his girlfriend Nereida Gallardo, Cristiano Ronaldo threw on his bright orange swimming trunks and hit the beach in Sardinia, Italy on Sunday (June 29).

The always-sexy soccer stud, along with his Spanish supermodel fiance, hopped aboard a $12 million luxury yacht that was rented out for a day of fun at sea.

The 23-year-old Manchester United hunk in currently in the midst of a month's holiday, which kicked off after Portugal's exit from Euro 2008.

According to press reports, Ronaldo is "predicted to return to Manchester next week and finalize a move to Madrid in time for the trip to Irdning for the start of pre-season training."
