Brighton players Anton Rodgers, Lewis Dunk, and George Barker, as well as former team-mate Steve Cook, who now plays for Bournemouth, had maintained their innocence.
Jurors at the Old Bailey also found them not guilty of voyeurism at the retrial.
The four men were given bail throughout the trial and their families, including Rodgers' father, Liverpool manager Brendan, watched the proceedings.
Jurors at an earlier trial in February could not agree verdicts but found Dunk not guilty of voyeurism.
Brighton this week released Rodgers.
