One minute, Serena Williams was happily sunbathing on Miami Beach, next minute, she became a self-confessed wedding crasher.
The tennis ace was spotted cosying up to a newlywed couple at the famous beach, dressed in nothing but her leopard-print swimming costume.
The bride looked more than happy about it, and spent a few minutes hugging Serena, who appeared to be over the moon she'd stumbled across the nuptials.
The Wimbledon winner even shared pics on her Instagram page, writing:"Wedding crasher! Congrats."
She also took the opportunity to show off her buns of steel, and captioned it: "Just right."
There was also a pic of her posing in her cossie in all its glory, and Serena wrote: "Leotard - swimsuit."
Serena jetted into Miami with fellow tennis star Caroline Wozniacki last week after losing in the second round at the French Open on Wednesday.
Caroline is enjoying a girls' holiday after recently splitting from golf star Rory McIlroy earlier this month.
According to the Daily Mail, Serena and Caroline have been letting their hair down with long days at the beach, and nights out after-dark. On Friday, the pair took in a Miami Heat vs. Indiana Pacers basketball game.
