Jennifer Aniston was out in her signature outfit of a tank top and jeans this afternoon in LA. The actress issued a statement earlier today dismissing reports romantically linking her to Justin Theroux. Justin, who costars in the upcoming movie Wanderlust with Jennifer, dined with her last night at one of her favorite hangouts, Sunset Tower. The outing sparked romance rumors, but Jennifer's rep pointed out that three other people joined them for the evening. He said: "It was a friends' dinner." Despite those false reports, there is positive news for Jennifer to focus on. It was announced this morning that at next month's Spike TV Guys Choice Awards, Jennifer Aniston will win sexiest star of the decade!

Jennifer Garner gave Seraphina a hand on the juggle gym at a park in LA today. The mother-daughter duo enjoyed the sunny weather after Jennifer and both of her girls checked out Adam Sandler's daughter Sadie's birthday party yesterday. Tobey Maguire and his oldest, Ruby, also stopped by the bash, where the kids got their faces painted and picked up balloon animals. Jennifer, Violet, and Seraphina stuck together since enjoying a weekend camping trip nearby, though dad, Ben, didn't join his family for the fun. He was recently spotted in Paris after another overseas visit that took him to Turkey to get started scouting locations for his film, Argo. Ben and Jennifer are both in the running for a spot on our PopSugar 100 list, so make sure to place your picks!

Jennifer Lawrence looked every bit the brunette bombshell as she arrived at David Letterman's studio for an interview, which will air during today's Late Night With David Letterman in NYC. She has been training hard to take on the role of Katniss Everdeen in The Hunger Games series, which meant missing the premiere of her new movie The Beaver at the Cannes Film Festival this week. We got our first look as Jennifer Lawrence as Katniss Everdeen in this week's EW, where the actress revealed her excitement over landing the role in the highly-anticipated book adaptation. For the past few weeks, she's apparently been working hard on her archery and stunt skills to take on the many fight scenes in the arena. They're almost done putting together the complete The Hunger Games cast, though we're still waiting on who will be Cinna. Jennifer will probably have a few breaks from preparations to help promote X-Men: First Class, which means more peeks at her transformation for fans of THG.

Pippa Middleton hit the streets in London this morning in her latest chic outfit as she made her way to meet friends at Harrod's for lunch. Kate Middleton's younger sister was decked out in head-to-toe blues and denim, which made for a slightly edgier look than her trademark Spring dresses. Pippa last put her fashion sense on display when she was on a weekend getaway in Spain. Pippa and her ex, George Percy, along with another of her girlfriends spent a few days in Madrid, where they shopped, took a boat out onto a lake, and partied late into the evening. The gang wrapped up the continental fun and headed back to the UK Sunday. Now that all the excitement over Kate and Prince William's wedding has wrapped up, Pippa's easing back into her own work life. She's a part-time employee at her parents' company, Party Pieces, and writes a blog for the business called The Party Times. Pippa spends the rest of her week working for another event-planning firm called Table Talk.
