Serena Williams really had an exciting weekend.
While on vacation in Miami, the tennis player was enjoying a beach day when she accidentally crashed a wedding.
"Wedding crasher!! Congrats!" Williams wrote on Instagram, in a series of photos from the event.
The tennis player, 33, who was ousted in the second round of the French Open recently, was enjoying a getaway with girlfriends, including newly-single Caroline Wozniacki.
Not long ago, Williams made it clear that she had her fellow tennis star's back following her split from fiance Rory McIlroy.
"I'll always walk with you," she wrote to her friend, who responded, "aww thank you!"
