Serena Williams had quite the dancing cameo in Beyonce's visual album Lemonade.
Williams, who danced alongside the singer in her music video for "Sorry," said she has known Beyonce "for a long time." She had to keep her cameo and the album a secret for months.
"If you tell me, 'Don't say anything,' I won't say anything," the tennis champion told WSJ Magazine in her cover story interview. Her close friend Caroline Wozniacki said Williams "really kept it a secret" and that she didn't know about the video until she saw it.
Williams and her sister Venus host a competitive event called the Williams Invitation every year, and one of the competitions is dance routines. Even so, dance lover Williams said that her Lemonade cameo was still a workout.
"I got really sore from dancing," Williams told the publication.
