Siesta Key Is Coming Back! Juliette Claims She Hooked Up with Ex Alex in New Promo Kompothecras, 25, revealed the pregnancy news on Instagram in December, sharing a photo of the couple kissing while the then-dad-to-be placed his hands on his girlfriend's baby bump. "Little princess on the way," he wrote in the caption, adding two heart-eye emojis. Soon after Kompothecras announced the pregnancy, his ex, Juliette Porter, came out swinging and claimed she hooked up with the dad-to-be while he was with Salerno. During Siesta Key's third season, which aired from January to March, Kompothecras came clean to Salerno about where things really stand with him and Porter, 22, after the exes had a lengthy conversation on the phone together.

"How is it not a big deal?" she said. "Your ex calling you and you're talking for six hours?" But things soon seemed smoothed over between the two, who continued throughout the spring to share cuddly photos together — including a stunning black-and-white maternity shot earlier this month. "I love you with all my belly 🖤 I would say my heart but my belly is bigger ☺️," Salerno captioned the photo, on which Kompothecras commented, "😍😍😍 I love you more xoxo."
