Celebrity Will and Kate's Celeb Scrapbook: All the Stars They've Met You get to hang out with Beyoncé, J.Lo and more A-listers By People Staff Published on December 12, 2014 10:00 AM Share Tweet Pin Email Trending Videos 01 of 13 JENNIFER LOPEZ Mark Large/Reuters/Landov Both J.Lo and Kate Middleton have worn dresses that will go down in history so they've got that in common. Perhaps that's what they talked about when the two, along with Prince William and Lopez's mom Guadalupe, hung out at the BAFTA Brits to Watch awards in Los Angeles on July 9, 2011. 02 of 13 REESE WITHERSPOON Tim Rooke/Rex USA "I don't know, maybe we can be friends," the actress told Ellen DeGeneres of her (hopeful) relationship with the Duchess after an evening spent with the royals in Los Angeles on July 10, 2011 at producer Steve Tisch's mixer. If this friendship blossoms, we've got their combined name all picked out: ReeKat. 03 of 13 LEBRON JAMES Tim Rooke/Pool/Getty A prince and princess meet King James. It sounds like a children's book, but it's actually what happened after Will and Kate watched the Cleveland Cavaliers beat the Brooklyn Nets in N.Y.C. on Dec. 8. The baller presented her with a "Cambridge" jersey (we imagine she'll belt it and wear it with Stuart Weitzman espadrille wedges this summer), plus one for George. 04 of 13 JAY Z & BEYONCE Geoff Pugh/Rex USA It's the stuff dreams are made of. We were so excited by the encounter in Brooklyn on Dec. 8 that we just had to imagine their conversations. All that's left to do is hope George and Blue Ivy have a playdate soon. 05 of 13 SIR PATRICK STEWART Kevin Mazur/Pool/Getty It's not his first rodeo. The X-Men and Star Trek star was knighted by the Queen in 2010, but this time it's the Duchess he gets to meet – and he brings his wife Sunny Ozell for the Dec. 9 event in New York City. 06 of 13 JENNA LYONS Christpher Wahl/Pool/Landov Our fingers are still crossed that this Dec. 9 meeting in N.Y.C. results in Kate doing a capsule collection for J.Crew. What, it could happen. 07 of 13 HILARY & CHELSEA CLINTON Tim Rooke/Rex USA Just two new moms from powerful families, hanging out. Chelsea, her husband Marc Mezvisnky and her mom mingled with the Brits at the Clinton Foundation's reception at the British Consulate General's Residence in N.Y.C. honoring the prince's work on Dec. 8. 08 of 13 EMMA WATSON & KATE MOSS Doug Seeburg/Getty Perhaps he told the Harry Potter star all about his visit to the set of her films? Whatever the conversation, Moss is entertained at a dinner to celebrate the work of The Royal Marsden cancer hospital on May 13 in Windsor, England. 09 of 13 RALPH LAUREN REX USA; Inset: Getty The iconic fashion designer looked more than pleased to meet the Prince at the Royal Marsden charity dinner – but Wills knew better: "I'm sorry my wife's not here. You probably would far rather [see] my wife." 10 of 13 JACKIE CHAN Chris Jackson /WPA-Pool/Getty The action star sticks with a simple handshake rather than a martial arts move when he greets Will on Feb. 12 at the National History Museum in London. Smart call. 11 of 13 TAYLOR SWIFT Dominic Lipinski/Reuters/Landov In royal hierarchy, who's more powerful – a pop princess or a prince? We'll check with the Queen and get back to you. But what we do know is T.Swizzle called Will "really funny" and "so cool" at the Centrepoint charity gala at Kensington Palace on Nov. 26, 2013. 12 of 13 DAVID BECKHAM Gouhier-Guibbaud-JMP/ABACA The longtime pals (the former soccer star and his wife Victoria were guests at the royal wedding) look right at home cheering on their team at the London Olympics on July 29, 2012. 13 of 13 BARACK & MICHELLE OBAMA Barcroft/Fame; Jacquelyn Martin/AP For their first post-honeymoon appearance, the royals welcomed the First Lady and President to Buckingham Palace on May 24, 2012.
