Victoria Beckham struck a pose on the red carpet in three different outfits at an event to reveal her latest luxurious project, the Range Rover Evoque special edition, in Beijing, China, on Sunday. Victoria spoke about the mini SUV, saying, "I brought a naivety to this project because I have never designed a car before. But it feels real . . . When I first started working with the team I did a lot of research, and created mood boards to show the team my love of timeless and classic design. I looked at yachts, luxury jets and classic cars."

Victoria brought her daughter, Harper, along for the trip to China, and she's been sharing their adorable travel outfits on her new Facebook page every day. Victoria also showed off her playful side with a series of snapshots of her journey in Asia. The Beckham girls are far away from their boys at the moment, though the whole family was together last week to celebrate Victoria's 38th birthday.

Ben Affleck chatted with his oldest daughter, Violet, after picking her up from ballet class in Santa Monica on Saturday. Ben and Jennifer Garner have been sticking close to home since welcoming their son, Samuel, at the end of February, though next week she is expected to make a quick trip to Vegas for CinemaCon. Ben's been hard at work on his next directorial project, Argo. Ben didn't travel back to Boston to attend Fenway Park's 100th anniversary celebration, but he did share his excitement about the Red Sox opening day on his Facebook page. Even though they're raising Violet, Seraphina, and Samuel in California, perhaps Ben will still get his little ones to join him and Jen in the ranks of celebrity Red Sox fans.

Rachel McAdams and Michael Sheen went grocery shopping together in LA on Saturday. Rachel matched her cute red flats and dress, which she accessorized with an Earth Day-friendly tote. It was another errand-filled afternoon for the duo, who have been spending most of their time together in California recently. Rachel skipped the premiere of his new movie Jesus Henry Christ last week, though they were side by side for an event in London earlier this month. There are rumors that Michael is considering popping the question to Rachel, but there's no sparkler on her finger just yet.

Kristen Stewart joined the crowds in Indio, CA, for weekend two of the Coachella music festival. She stayed incognito thanks to boyfriend Robert Pattinson's Orioles hat, which she paired with a tiny tank and short shorts. Kristen is one of the many celebrities at Coachella who opted to skip the madness and party scene of the first weekend. Robert wasn't by Kristen's side in the desert on Saturday, though the two have an exciting month coming up together. Robert and Kristen are needed back in Vancouver to do some Breaking Dawn Part 2 reshoots in the coming weeks, but then it's time for the fun stuff. Both Rob and Kristen have movies headed to the Cannes Film Festival, so hopefully they'll stick together on the famous croisette red carpet.

Kristen will also be out promoting Snow White and the Huntsman soon, and you still have a chance to interview her in person. Enter our I'm a Huge Fan contest for a chance to win a trip to meet Kristen Stewart in London!

Justin Bieber got a surprise visit from girlfriend Selena Gomez on the set of his music video shoot in LA on Saturday. In between takes, Selena jumped into Justin's arms and engaged in some sweet PDA. The young lovebirds can't keep their hands off each other, though earlier this week Selena admitted to being a bit embarrassed when they were forced to kiss courtside at the Lakers game. Justin and Selena ended up on the kiss cam, and when she stopped by to chat with Ryan Seacrest for his radio show later in the week, she revealed that the moment on the Jumbotron was "so awkward." Selena's busy week also included an event to launch her new fragrance, which hits stores in May.
