Alex is expecting his first child with girlfriend Alyssa, but how did he reveal the life-changing news to those closest to him?

In an extended sneak peek of Siesta Key, premiering tonight, the King of Sarasota is heard uttering the words, "She's pregnant." We don't see anyone's direct reaction -- except a brief shot of Juliette crying.

But there's more: Someone declares "I'm late" -- so another Siesta mini-me could be making a debut. Who is it? Watch the clip to see more, and do not miss the premiere of Siesta Key tonight at 8/7c!
