The evidence was right in front of our eyes this whole time!
The news shocked us all, including her hubby (and Simon's bestie) Andrew Silverman — who filed for divorce weeks ago, citing Simon as a co-respondent in the papers.
But as you can see in the photo (above), the sparks appear to date back to at least January 2012, when Simon and the Silvermans took a hot vaca to St. Barths.
Ch-ch-check out more pics of Lauren and Simmerz (below)!
There's even one with Andrew too! But from what it seems, he and Simon didn't share nearly as much balcony time as Lauren got!
