14 Celebrity Wedding Crashers

One of a bride's biggest fears? Uninvited wedding guests showing up at their ceremony or reception. But what happens if that wedding crasher happens to be Beyoncé or Brad Pitt? Chances are, you probably wouldn't be dismayed if that type of wedding attendee showed up!

This has actually happened to a few lucky brides and grooms and we, along with the rest of the world, are beyond jealous. Turns out, when the wedding crasher is a famous actor, musician, or politician, the unwelcome surprise is actually quite, well, welcome. And it makes for amazing wedding photos—plus, a great story you can retell for many years to come. Take the bride-to-be seen here, for example: She was about to walk down the aisle when she spotted the one and only Queen Bey! What would you do if you were in her position? Ask the superstar for a photo, of course. Beyoncé and Jay Z were vacationing in Portofino, Italy in 2014 when they decided to make a cameo at a wedding that was unfolding.

On a day that is sure to be one of the most memorable of your entire life, a surprise celebrity appearance—whether it's planned by a loving spouse or completely random—is only a bonus. Although the odds of your absolute favorite star (from your absolute favorite TV show) making an appearance at your ceremony or reception is relatively slim, crazier things have definitely happened. Here, famous faces who've crashed weddings and even posed for photos with the brides and grooms. Talk about the most memorable or Instagram-worthy moment of the night!

Orange is the New Black

cast members Lea DeLaria, Yael Stone, and Danielle Brooks worked together with an Australian bride to help her surprise her unsuspecting wife on the wedding day. The co-stars were already down under to partake in the annual Sydney Gay & Lesbian Mardi Gras when they heard that brides Tegan and Louise, both diehard fans of the Netflix show, were getting hitched. As a special surprise, they "crashed" the reception, where DeLaria, also a Broadway star, performed a rendition of Ella Fitzgerald's "Taking a Chance on Love." 

Bradley Cooper surprised this couple while visiting his alma mater, Georgetown University, where the wedding took place. Not only did he shock the bride and groom when they were taking pictures on campus, but he even caught the bouquet!

Tom Hanks crashed this couple's wedding photos in Central Park in New York City. Best part? While talking to the couple, he offered to officiate their wedding!

At the father-of-the-bride's request (he ran into JT earlier that day), the pop star popped in on this bride and groom's big day, surprising them during their first look. "So we were taking the first look photo and all of a sudden Justin Timberlake appears out of nowhere, shakes my husband's hand, and congratulates us and takes a photo," the bride told ET

. "We thought it was awesome of him to do that, but had no idea it would go viral." Best. Wedding gift. Ever.

In 2013, Brad Pitt was enjoying a drink at the Maidenhead hotel bar in Buckinghamshire, England when a bride and groom spotted the actor. Brad happily obliged to a photo, but, sadly, he did not join the dance party.

This lucky bride accidentally bumped into Robert Pattinson at her wedding reception in Northern Ireland in September 2015. But this wasn't Pattinson's first time crashing a wedding—he popped up at a wedding rehearsal with Katy Perry in Montecito in 2013.

What started out as a romantic beach wedding in Miami in 2014 turned into a party with tennis pro, Serena Williams. The unsuspecting couple snapped a pic with the reigning Wimbledon champion who wasn't exactly dressed for a formal wedding.

Justin Bieber and Selena Gomez were driving around Malibu in 2011 when they heard Bieber's hit "One Less Lonely Girl" playing at a party and decided to go in. It turns out that the party wasn't just a party—it was a wedding reception! Justin and Selena stayed for 10 minutes to say hello to the newlyweds before leaving.

The blushing bride-to-be met LeBron James at the Ritz Carlton Coconut Grove while James was wrapping up a Sports Illustrated interview in 2013. The 6'8" basketball star was all smiles with the bride and groom, who were huge fans of the player.

While so many couples choose Ed Sheeran's ballads for their first dance song, this couple got Ed Sheeran to sing live at their reception. The Australian newlyweds got the ultimate surprise when Sheeran came to the wedding unannounced and performed his hit, "Thinking Out Loud" in 2015.

Minutes before walking down the aisle at Torrey Pines Gold Course resort venue in San Diego in 2015, this bride and groom spotted President Obama finishing a round of golf. When he finished playing his round, the President joined the reception to congratulate the happy bride and groom.

When Whitney Houston's "I Wanna Dance With Somebody" starts playing at a wedding (or anywhere for that matter), you get up and dance—even if you're Kendrick Lamar. The rapper surprised wedding guests by walking into the reception and busting out his best dance moves to the classic wedding jam in Columbus, Ohio in 2015.

While in Washington, D.C. to raise awareness for drug addiction and substance abuse, the "Can't Hold Us" singer crashed a wedding in a hotel with encouragement from his mom, Julie Schott! Of course, his and Ryan Lewis's song "Thrift Shop" played while the rapper and guests danced and clearly had a great time, all thanks to his mom.

Max Singer and Kenya Smith had previously officially tied the knot in the groom's mother's hospital room so she was able to witness her son's big day. The mother and son also danced to their favorite song, Taylor Swift's "Blank Space." After his mother's passing, the groom's sister-in-law contacted Swift to tell her about the loss of their family member and asked her to surprise the newlyweds at the wedding celebration. Not only did the superstar surprise them, but she also sang a piano version of "Blank Space" and brought a handmade gift, too! One thing's for sure, Taylor Swift will pretty much do anything for her devoted fans.
