Josh Hartnett signed autographs in London yesterday, but he doesn't have love for everyone. He's suing the UK's Daily Mirror for claiming there was a security video of him hooking up with a girl in a hotel library. His lawyers called the story "not only untrue but a complete fabrication," and asked for a public apology as well as damages for defamation. Hopefully Josh can stay distracted from all the gossip as he keeps rehearsing for his Rain Main debut, which has been pushed back to Sept. 19.

Sienna Miller didn't look too pleased with all the attention arriving at LAX on Sunday and heading over to a Pilates class in Hollywood on Monday. Most of you don't feel bad for Sienna and the negative press she's been getting because of her relationship with Balthazar, and the publicity probably won't improve if she moves to LA with him. Hopefully Sienna can keep a low profile and avoid any more gas station scenes as she goes about her business on the West Coast.

Honor Warren had her very first flight just a couple of weeks ago, and it looks like Jessica and Cash have a junior globetrotter on their hands already. Jessica was spotted making her way around NYC this morning, showing off her baby girl for the first time since Honor's first photo shoot. We'll have to wait and see if Jessica's in town for Fashion Week or just for a vacation, but maybe we'll hear all about it on one of the family blogs later this week.

Straight off her weekend at the Toronto Film Festival, Jennifer Aniston hopped down to NYC to join her good friends Courteney Cox and David Arquette for the launch of David's new menswear line, Propr, at New York Fashion Week. The collaboration between David and Ben Harper was celebrated by their wives and was even family-friendly enough for their kids — like Coco, who strapped on her Mary Janes and climbed on mom's shoulders to get better view of the action. Courteney and Laura Dern have been hanging out in Manhattan with their daughters before their husbands' big night, but Cox looked great posing with her BFF Jennifer Aniston when she arrived on the scene.

Sarah Jessica Parker sported cuffed jeans and a Summer scarf on Monday while running errands before spending time with James Wilkie and Matthew Broderick. She had James's backpack to hold along with her Bitten tote bag as the family gears up for back to school time. The actress's Obama fundraiser with Anna Wintour is today, but hopefully we'll get a glimpse of her at even more Fashion Week-related events. Now that her clothing line has been saved, Sarah Jessica can keep on designing — not that this fashion-forward gal needs a job to stay stylish.
