Jessica Simpson

Jessica Simpson and her frequent flyer pooch, Daisy, arrive in New York last night.

Hayden Panetierre

A celeb with a cause is a great thing. For Hayden Panetierre, her passion is saving sea animals. On Sunday the 18-year-old star showed up at a Washington, D.C. demonstration that called for a stop to whale hunting. She spoke to the crowd, saying, "Not only are these animals being cruelly slaughtered, the meat is contaminated by huge levels of mercury. And we're not taking a stand because Japan is one of our biggest allies in the war on terror, but Australia is an ally and they've told Japan what they think, and good on them!"

Last fall she participated in a rally to protest the killing of dolphins in Japan. And she's not done yet. Hayden is visiting the embassies of Iceland, Norway and Japan to discuss the cause. She also has a Web site, Panettiere's Closet, that is selling clothes and accessories from her show. All proceeds go to the Whaleman Foundation.

Pete Wentz and Ashlee Simpson

Ashlee Simpson hangs on to the coffee while boyfriend Pete Wentz takes care of the food and their dog, Hemingway. They dropped by a pet clinic to have him checked out yesterday.

Brit Brit and Pup

Brit Brit headed into the Millennium Dance Complex in North Hollywood last night (after picking up a birdcage and dog food at Petco) to start working on moves for her next video for "Hot as Ice." The routine involves some chair dancing like she did in the "Stronger" video.

On Saturday night, Britney invited two new cameramen into her home for champagne and to discuss her relationship with Adnan. Her manager Sam Lufti stated that they have filed a restraining order against Adnan. Police denied any restraining order had been filed and Adnan stated that he was out of town for the weekend and was not aware there was any problems in his relationship with Britney.

Britney Spears

Britney Spears cuddles with her Yorkie, London, at a gas station in Brentwood. Britney's mom has blasted Dr. Phil for making a statement after visiting Britney in what was supposed to be a private consultation. She claims that he has created more distance between Britney and her mom and sister.

Mariah Carey models her baby GAP clothes and hooker heels while walking with her new Jack Russell terrier in South Beach.

Paris Hilton

Paris Hilton poses with (I think) Tinkerbell for a Christmas photo during the annual holiday shoot at her family estate.

Rebecca Romijn and Jerry O'Connell

Rebecca Romijn and her husband Jerry O'Connell take their two pooches with them to pick out a Christmas tree at Home Depot in Calabasas. His and hers pups.

Vanessa Hudgens

Vanessa Hudgens brings her pup Shadow with her on a trip to the recording studio. High School Musical 3 begins filming early next year so she could be working on tracks already!

Paris Hilton

Paris Hilton took one of her Chihuahua pups shopping with her at Kitson. Poor thing looks terrified!

Carrie Underwood

Back in New York after her success at the CMAs, Carrie Underwood carries her pup as she walks with new boyfriend Gossip Girl's Chace Crawford. Carrie recently said that she hasn't had too much of a problem with the paparazzi until her recent trips to New York. She said that she worries about walking her dog because she knows they will be out there to catch her as she's waking up or at the end of the day. Guess she knows what she's talking about!

Ashley Tisdale

Ashley Tisdale heads to a promotional gig for her single He Said, She Said with her Malitpoo puppy, Blondie, in tow.

Demi Moore

Demi Moore totes her puppy as she exits her apartment in New York yesterday. She and the pooch were off to visit her husband, Ashton Kutcher, on the set of What Happens in Vegas.

Britney Spears

Britney Spears goes for a drive with her Yorkie London before turning herself in at Van Nuys jail last night. London wore a shirt that match Brit Brit's latest wig. Pretty in pink?

Hayden Panetierre

Hayden Panetierre takes her dogs Madison and Penny Lane out for a walk (or for a carry if you're the Maltese). I love that she is hands-on with her pups and tries to spend lots of time with them when she isn't out working (which isn't much)!

Rachel Bilson

Rachel Bilson carries her dog, Thurman Murman, from the vet. I think when she split from Adam that she got this pup and he kept Penny Lane, their rescued Pit Bull.

Kate Beckinsale

Kate Beckinsale and her husband Len went shopping together on Robertson Blvd. and stopped at a pet store along the way to play with kitties.

Jessica Simpson

Jessica Simpson boards a plane out of LAX with her pup, Daisy, yesterday. Quite dressed up to fly, aren't we?
