I Love Lucy: Season 1, Episode 10 - ProjectFreeTV

1 - 10: Lucy is Jealous of Girl Singer

An item in the morning gossip column prompts Lucy to assume that Ricky is seeing another woman, namely Rosemary, one of his dancers. To keep an eye on Ricky, Lucy manages to wangle her way into the chorus line of "Jezebel" at Ricky's club and upstages Rosemary during the number. Later that night, Ricky tells Lucy that there was a "strange girl" in the chorus-ugly, and a terrible dancer. He knew it was Lucy all along. They kiss and make up.
