Mark Hamill said it himself: "loose lips sink starships." But it seems that he didn't quite follow his own advice for Star Wars: The Rise of Skywalker. In a tweet, Mark shared that, for the next Star Wars cameo, "all signs point to one direction" and followed up with "#Stylestrooper." Mark's tweet started a whirlwind of speculation. Is Harry Styles in Rise of Skywalker?

Mark Hamill started the rumor that Harry Styles is the next Star Wars cameo.

Whether Mark knew it would happen or not when he tweeted out a photo of Harry Styles in a Stormtrooper uniform with #Stylestrooper, he started a rumor that spread throughout pretty much every entertainment magazine. And it made Harry's fans very hopeful for his cameo.

One of the big issues with this theory was that Mark didn't share a picture of Harry on set. He shared images of known cameos in previous Star Wars movies, including Daniel Craig, Prince Harry, and Prince William. They were all in their official Stormtrooper costumes. But Harry's picture came from a Halloween party earlier this year.

Still, fans took the rumor and ran with it, which led to Mark addressing what happened on Twitter. In his tweet, he apologized — not for starting the rumor, but for having spoiled the big secret. He then asked fans to avoid all future spoilers and said that they need to wait to see the movie to figure out who Harry is.

Is Mark telling the truth? Not according to Daisy Ridley.

Mark Hamill is kind of a known prankster and spends a lot of time engaging with fans on Twitter. He responds to Star Wars questions and sometimes what he answers is an emotional memory. Other times, it's a joke. He's also known for sharing many, many Star Wars memes. So perhaps we should analyze his tweets with that context.

According to Daisy Ridley, in an interview with Capital FM, she doesn't believe that Harry is in the film. When asked if Mark's tweet was a real spoiler, she responded, "I don't think that's true. I'm pretty sure that he's not in. And if he is, I'm pissed that I didn't meet him because I love him. I don't think he is. Was [Mark] confused with Ed Sheeran?"

Ed Sheeran has a confirmed cameo in Rise of Skywalker, along with Lin-Manuel Miranda. Ed and Lin both appeared in costume in a video posted by the official Star Wars YouTube account that gave fans a look at Rise of Skywalker's production. Lin is expected to play a Resistance fighter while Ed is a Stormtrooper.

So who's telling the truth? Daisy or Mark? Unfortunately for us, whether we see Star Wars: The Rise of Skywalker, we still won't know because Stormtroopers keep their faces covered. So we'll just have to wait to see if Harry weighs in and reveals the truth. 

Rise of Skywalker is in theaters Dec. 20.
