Jon Gosselin is opening up about a health scare he had before his wedding - and he says it could've killed him! In case you didn't know, the Jon & Kate Plus 8 star got married to his girlfriend Stephanie Lebo in November 2025. Just weeks before the big wedding, though, he suffered a health issue that almost put everything on pause. While speaking to DailyMail.com at the Sundance Film Festival over the weekend (he's got a good DJ gig there), he gave more details as to what actually happened.
