Juliette Porter Disses Her 'Siesta Key' Costar Before Season 3 Premiere

If you didn't know before, Juliette Porter is not one to mess with.

The "Siesta Key" star has proven time and time again that she has no problem speaking her mind, especially when it comes to someone doing something shady. So, when she sent out a tweet Monday night about her co-star Cara Geswelli, it wasn't exactly out of character.

"Cara is a shady skank and she [expletive] @johnnybananas while dating @__GarrettMiller in Cancun," Juliette wrote.

"Cara from our show lol," she followed up to clarify just who she was talking about so there was no confusion.

Although the tweet wasn't exactly surprising (she recently called out her ex and "Siesta Key" costar Alex Kompothecras), it did leave fans wondering what exactly triggered the social media outburst.

As a reminder, Cara came onto the scene during Season 2 and dated Garrett Miller (Juliette's ex). As far as fans know, based on the season finale, the two were still together and working on their relationship. What happened between then and now is a puzzle that is still being put together.

Thankfully, though, Garrett and Cara's relationship will be one of the Season 3 storylines so viewers will hopefully start to understand what happened -- or maybe Juliette will have another outburst -- in either case, it's just a matter of time.

Siesta Key" Season 3 premieres Tuesday, Jan. 7 at 8 p.m. on MTV.
