Sam Asghari Files for Divorce from Britney Spears

Our sources say there's an "extensive confidentiality clause" in the prenup, prohibiting Sam from talking about his relationship with Britney. So on the surface, it seems Sam's getting nothing of significance, but that's not the case.As we reported, Sam's lawyer, Neal Hersh, filed divorce docs which ask for spousal support. Given the prenup precludes such support, Hersh's move signals a challenge to the prenup.
