Mary-Kate and Ashley Olsen were both in black to host a cocktail party for Elizabeth and James at Saks Fifth Avenue in NYC last night. The designing sisters have been focused on fashion since kicking off NYFW at the beginning of the month. They also took their love of clothes on a shopping trip to Alexander McQueen before their upcoming trip to Paris, where Mary-Kate and Ashley will be presenting The Row this Sunday during the city's Fashion Week. Check out video of the girls discussing their lines and stay tuned on Fab, Bella, and Fashionologie for all the updates from France!

Stephanie Pratt was out for another bikini lounging session at her LA home this afternoon. The former star of The Hills seems to be perfectly at home in her two-piece, whether she's doing mundane tasks like cleaning her pool or being social partying with friends at a barbecue. She shares a knack for starring in photo shoots with her brother Spencer, who should break out the candles and sparklers to celebrate a few good things in his life. On top of releasing a trailer for his new movie, he and his estranged wife, Heidi Montag, have apparently called off their divorce! That should mean lots more canned posing from the duo, whether they're marking birthdays, getting political about the upcoming elections, or just chilling at the beach.

Kellan Lutz stayed hot and hydrated leaving the gym after a workout in Sherman Oaks, CA yesterday. He's maintained his muscles in preparation for filming the final Twilight saga installments and showed us the fruits of his labors with a sexy shirtless basketball match earlier in the week. Kellan also lends that famous six-pack to Calvin Klein underwear ads, much to the delight of his fans around the world. One thing Kellan cares about as much as fitness is his beloved dogs Kevin and Kola, though the pups may have to stay behind when he goes on location for Breaking Dawn. In other saga news, his costar Robert Pattinson reemerged in LA with his big bushy beard and we also finally got to meet Renesmee.

The Rossdale boys hit up an Urban Outfitters in LA yesterday accompanied by a nanny rather than their usual platinum blonde, Gwen Stefani. Kingston made funny faces in some oversized sunglasses and held hands with his littler brother while Gavin scoped out the maxi dresses. Gwen was busy in the studio with No Doubt as her adorable guys shopped away. Gavin had both his sons and Gwen there to cheer him on over the weekend when he reunited with his band, Bush, for a show, though he lamented the fact that his friend Mario Batali couldn't make it. The Stefani-Rossdale family is settling into the Fall at home, and as of tomorrow it's officially October, which means a month full of dressing up and pumpkin patch visits for costume-loving Kingston and Zuma!
