People.com Entertainment TV 'Siesta Key' 's Juliette Porter Accuses Cara Geswelli of Cheating on Boyfriend with Johnny Bananas The accusations came ahead of Siesta Key's season 3 premiere By Dana Rose Falcone Published on January 7, 2020 05:57 PM Share Tweet Pin Email This is one messy MTV love triangle. The night before Siesta Key returns for a third season, Juliette Porter accused costar Cara Geswelli of cheating on her boyfriend Garrett Miller with fThe Challenge’s Johnny “Bananas” Devenanzio. “Cara is a shady skank and she f*ckrd @johnnybananas while dating @__GarrettMiller in Cancun,” Porter, 21, tweeted on Monday. Miller, 24, replied only with a GIF from the 1994 movie Little Rascals of the character Porky resting his chin on his hands. MTV couldn’t be reached for comment. While Geswelli could not be reached for comment, in the trailer for season 3, she says, “If I’ve learned anything, it’s to stop cheating and to stop lying because people will find out about it.” Cara Geswelli/Instagram, Paul Archuleta/FilmMagic; MTV When commenters asked Porter how she knew about the alleged cheating, she claimed that Floribama Shore’s Nilsa Prowant “told me.” Porter posted Instagram Stories on Monday night that show her hanging out with 26-year-old Prowant, along with her Siesta Key costars Kelsey Owens, Chloe Trautman and Amanda Marie Miller. Season 2 ended with Geswelli and Miller leaving their relationship in an uncertain spot when she left for a family trip to Italy. Porter and Geswelli’s feud is nothing new due to Geswelli’s past relationship with Porter’s then-boyfriend Alex Kompothecras. When Geswelli returned to Siesta Key, Florida, in the show’s second season, Porter thought Geswelli was flirting with Kompothecras, 24, and wanted to get back with him.
