Lindsey Sweetwater is a minor character in The Loud House.
Lindsey is first mentioned in "Making the Case", as the winner of a beauty pageant, in which Lincoln was competing.
She reappears in "Fool Me Twice", where Lola's lookalike admires and gives her one of Lola's pageant crowns. This is the first time she physically appears onscreen.
Lindsey is a young girl who is the same height as Lola, and has long hair that curls up at the bottom. She wears lipstick, a bow on her head, white pearl earrings, long evening gloves, a dress with frills at the bottom, and a belt to hold it up.
Because she was only seen on a single colored monitor, the colors on Lindsey can't be fully determined.
Lindsey is a competitive beauty pageant participant, and does her best to win them. Despite her efforts, Lindsey always takes second place to her eternal rival, Lola, which annoys her to no end. Driven by envy, she's determined to defeat Lola, or give her trouble. When she heard Lincoln was seeking something to blackmail Lola with, she used that opportunity to help him, but also made it clear that she's not Lincoln's friend.
