Las Vegas played host to not one but two major parties this weekend. Kris Humphries and his posse of friends, including soon-to-be brothers-in-laws Lamar Odom and Rob Kardashian, partied together last night at the Palazzo's Lavo night club. A few hotels away his fiancée Kim Kardashian simultaneously celebrated her bachelorette at Tao. Kim let loose alongside her sisters, Khloe and Kourtney, and her mom, Kris, until 2 a.m. when the ladies then dropped in to crash Kris Humphries's bachelor party. Kim and her crew didn't stay long but she did share a sweet kiss with Kris before resuming her girls' only soiree. Today Kris was once again without his bride-to-be, Kim, though he made the best of his time in Sin City by enjoying a shirtless afternoon at Tao Beach. The pair is closing in on their big day with rumors Kim and Kris are planning to walk down the aisle Aug. 20.

Kristen Stewart was back at Comic-Con in San Diego today sitting on her second discussion panel of the week. On Thursday she joined Robert Pattinson, Taylor Lautner, and the Breaking Dawn Part I cast to share new details about the highly anticipated wedding and honeymoon scenes, as well as what it was like giving birth to a vampire baby. Today, however, Kristen was excited to talk about a new project, Snow White and the Huntsman. She was joined by costars Charlize Theron, Chris Hemsworth, Sam Claflin, and director Rupert Sanders, who surprised the crowd by debuting the first images of Kristen and the rest of the cast in their Snow White and the Huntsman costumes. Kristen, who plays Snow White, wields a shield and full suit of armor in the promotional photos opposite Charlize, who poses as the Wicked Queen in a dark and haunting portrait. Chris is back in full battle gear for his role as the Huntsman, though this time he's been given an ax as protection instead of the mighty hammer he carried in Thor. During today's panel Charlize jokingly challenged Kristen to a fight, saying, "I'm ready for it, b*tch, let's go." Kristen in turn said she's eager to work with "really cool weapons" in addition to doing "sword stuff."

Reese Witherspoon and Jim Toth set out early from their Parisian hotel yesterday. The newlyweds are in France celebrating their honeymoon while Reese's kids, Ava and Deacon, are on their own getaway with dad Ryan Phillippe. Reese and Jim have been spotted all over Paris exploring the city's historical landmarks and museums, and yesterday they took a break from sightseeing to shop. During her January trip to Paris, Reese made a purchase at Louis Vuitton; this time she dropped in Hermés and left with one of the luxury brand's iconic orange shopping bags.

Harrison Ford stepped out with his lovely wife, Calista Flockhart, for last night's San Diego premiere of Cowboys and Aliens. Newlywed Daniel Craig arrived solo as did his stunning costar Olivia Wilde in a floor-length, lace Dolce & Gabbana gown. Their sci-fi Western was a big draw at WonderCon this Spring, and it's no surprise director Jon Favreau picked Comic-Con as the perfect location for the film's world premiere. Thousands of fans turned out for the screening including a few Hollywood stars like Ron Howard, Nina Dobrev, and Seth Green. The red carpet affair caps off an exciting week for Daniel. His live-action animated project The Adventures of Tintin earned tons of buzz during a Comic-Con panel while another one of his projects, Dream House, released its first full-length trailer. The haunting thriller brought Daniel and Rachel Weisz together, but we'll have to wait until the Sept. 30 release to see if their real-life chemistry translates to the big screen.

Cameron Diaz and Alex Rodriguez stopped by a Whole Foods in Miami to load up on groceries late yesterday. ARod is recuperating in South Florida following a surgery he had earlier this month to repair the torn meniscus in his right knee. He's not expected to return to the Yankees until next month, so the break in his schedule gives him the opportunity to be closer to Cameron while she's shooting What to Expect When You're Expecting in Atlanta. Cameron's joined by newly single Jennifer Lopez, Brooklyn Decker, and hot guys Chace Crawford and Matthew Morrison in the comedy based on a popular parenting manual. It's been a busy Summer for Cameron, promoting Bad Teacher and shooting Gambit in the UK, but hopefully she'll have a few more days off to celebrate Alex's 36th birthday with him on July 28.
