Justin Timberlake held true to his word and accompanied Corporal Kelsey DeSantis to the Marine Corps Ball in Richmond, VA on Saturday evening. Justin looked sharp in a tuxedo for the event, and afterwards he wrote a lengthy, emotional piece about Kelsey and everyone he met at the ball. JT gushed about meeting his "heroes," the men and women who serve the USA in the armed forces, and even hit the dance floor with Kelsey and her friends. Justin had to leave before the evening was over, but it sounds like he gave Kelsey and her buddies a night to remember. Kelsey originally asked Justin to the gala over YouTube after his friend and Friends With Benefits costar Mila Kunis got and accepted a similar invite to another military bash.

Justin started his piece writing, "I knew I would have an evening that I wouldn't forget... Something I could tell my friends about. What I didn't know was how moved I would be by the whole experience." Justin went on to say, "I felt so proud to be there. I felt like I was getting a chance to be among my heroes. It's funny too because a lot of them are SO younger than me." He finished it off by thanking his date, "Thank you Corporal Kelsey DeSantis. Thank you for inviting me. And, thank you for being my hero." Read Justin Timberlake's whole piece on his website.

Victoria Beckham made sure that both she and her daughter, Harper, were looking their best as they arrived at LAX for their flight to NYC this afternoon. Victoria tweeted that her own dress is from the Victoria Beckham Collection, the boots are Christian Louboutin, and Harper is wearing Maison Bonpoint. The Beckham girls are headed to the East Coast where Victoria will speak at a Women's Wear Daily conference.

Victoria wrapped her arms around husband David Beckham while they watched their sons play soccer on Saturday, and the whole crew went out to dinner at Dan Tana's on Saturday night.

Brad Pitt and Angelina Jolie paid a visit to the Con Dao Museum in Vietnam today. Con Dao is an island that used to be a prison, and the buildings that formerly held the captives have been converted into the museum. Brad and Angelina were photographed without any of their kids, though all six did come along on the journey to Pax's native country. It's Pax Jolie-Pitt's first visit back to Vietnam since his adoption in 2007. Angelina brought her four older kids along to Cambodia earlier in the year when she shot her Louis Vuitton ads, so Maddox also recently got a chance to check out where he was born.

Britney Spears waved to fans from the balcony of her hotel in Rio de Janeiro today. Britney is kicking off the South American leg of her Femme Fatale tour in Brazil and will continue through the continent for the next couple of weeks before wrapping things up in Mexico and Puerto Rico in early December. It's been a long international road for Brit, but luckily she has her main men around to ensure she doesn't get too homesick. Britney's boyfriend, Jason Trawick, joined her on the balcony this morning, and he's stuck by her side for all her shows. Britney skipped the beach, but on both Friday and Saturday her sons, Sean Preston and Jayden James, hit the waves with their grandparents Jamie and Lynn Spears.

While Britney is on the road, she had some fun news to celebrate back at home this week — Britney is nominated for a favorite album of the year People's Choice Award!

Nicole Richie played host to a number of celebrity parents and their kids at a Winter Wonderland event with Baby2Baby and Huggies in LA on Saturday. Nicole didn't bring her two little ones, Harlow and Sparrow, to the bash, but Rachel Zoe and Rodger Berman did pose with their son, Skyler. The stylish 7-month-old was in all gray, which made his big blue eyes stand out. Rachel didn't break out Skyler's adorable Gucci tuxedo this time, though it's going to be pretty adorable when he does get black-tie formal. Rebecca Gayheart, who is pregnant with her second baby, joined husband Eric Dane and their first daughter, Billie, while Busy Philipps got crafty with tuxedo-shirt-wearing Birdie. Cash Warren brought Honor to get her face painted while his wife, Jessica Alba, traveled back from Milan with their younger baby, Haven.

Victoria Beckham wrapped her arms around husband David Beckham as they watched their sons, Romeo, Cruz, and Brooklyn, play soccer in LA on Saturday. Becks and LA Galaxy teammate Landon Donovan joined the boys for practice on Friday, though the all-star dad stuck to the sidelines for the actual game. Harper Beckham stayed in her stroller this time around, though she did poke out her adorable face to see her dad win a big championship with the LA Galaxy last week. Harper Beckham has become a staple in the luxury box during David's games this season, and the whole family will have one more chance to cheer him on as he competes for the MLS Cup next Sunday.

The Duke and Duchess of Cambridge stepped out at the Cenotaph in Whitehall on Remembrance Sunday today to commemorate those who have died in war serving the country. It's Catherine's first Remembrance Day as a member of the royal family and she was in classic black, which went for all the women at the event. Still, Kate mixed up her look by sporting two poppies on her Diane von Furstenberg coat and a fascinator by Jane Corbett. Nearby, Prince William somberly saluted the fallen soldiers and laid a wreath down on the war memorial.

It's been an exciting week for Prince William and Kate Middleton, who attended a black-tie gala side by side on Thursday. Kate Middleton wore a one-shoulder Jenny Packham gown for that occasion. Newlywed Kate and William are the subjects of recent pregnancy rumors, so every fashion choice she makes is examined more than ever. The palace has yet to comment on the reports, though perhaps the happy couple will wait until after Prince William has to spend months apart when he is deployed to the Falkland Islands as part of his Royal Air Force duties next year.

The Muppets shut down Hollywood Boulevard in LA yesterday for the world premiere of their new movie. Kermit the Frog was joined by his whole crew — Gonzo, Rolf, Animal, Fozzy, and newcomer Walter — arriving in a Jeep to kick off the green-carpet processional of stars and puppets. Miss Piggy followed closely behind in her own convertible, wearing Jeremy Scott and Louboutins, and blew kisses to the crowd. We talked to Piggy and Kermit about their return to the big screen, and the pair joked that this film brought them closer together.

We also spoke with some of the human stars including Amy Adams and Jason Segel. Jason said it was a dream come true to work with the Muppets and he plans on inviting all of them, including his puppet brother Walter, over for Thanksgiving dinner so they can reenact the landing on Plymouth Rock. Many of Jason's How I Met Your Mother costars also stepped out to support his latest venture including Alyson Hannigan, Josh Radnor, and Neil Patrick Harris, who has a small role in the film. Meanwhile, Amy spoke with us about the importance of making family films and working with the ultimate leading man, Kermit — stay tuned for more of our interviews with the cast in PopSugar Rush!
