The MTV Movie Awards 2013 - Arrivals - Los AngelesBut who will constantly tell Ron to STAHP without Sammi?

Most of the "Jersey Shore" cast is reuniting for "Jersey Shore Family Vacation," with the notable exception of OG drama queen Sammi "Sweetheart" Giancola. Why isn't she joining them? As you might expect, Ronnie Ortiz-Magro is connected to her reason.

Here's what a source told Us Weekly:

"Everyone was invited to come on the show but Sammi was the only one who didn't want to. A big reason for that was because she didn't want to be around Ronnie. She has been enjoying her life off of TV and didn't want to change that."

Sammi and Ron were on-and-off for years, breaking up for good (or so we think) in 2014. Last spring, Sammi showed off her new boyfriend, Christian Biscardi. She told E! he was not in the business, and she was hoping to keep their relationship more private, unlike her very public life with Ronnie. "It's refreshing."

She's still gushing about him on Instagram, often sharing photos like this:

So in love with this man. ♥️

So you can imagine why she wouldn't want to step back into the "Jersey Shore" drama, especially when MTV would be wanting her to spar with Ron.

Fans already miss her, though:

Don't worry. "Jersey Shore Family Vacation" will probably have enough drama without her. It's expected to air in 2018.
