For the cast members on Jersey Shore: Family Vacation, what happens in Vegas does not stay in Vegas.

It gets broadcast to millions of viewers each week!

There's good news for Jersey Shore fans: Deena Cortese is pregnant with her first child!

Deena and her husband, Christopher, are expecting a baby boy within the next six months.

Finally, folks:

A Jersey Shore story that has nothing to do with booze or fighting or violent acts perpetrated on a cast member by an angry baby mama.

Jersey Shore Family Vacation made its long-awaited debut on MTV last night, and the consensus among viewers seems to be that while the guidos and guidettes didn't quite deliver the same bonkers energy and smush-room shenanigans of their initial run, it was nice to check in with TV's most heavily spray-tanned cast.

Of course, not everyone was able to make it to South Beach to enjoy all the fist-pumping and facial fillers.

Once upon a time, MTV's Jersey Shore was garnering higher ratings than some of the biggest shows on broadcast TV. 

Nowadays, the network rarely charts in the ratings and is returning to old formats in an attempt to bring the network back to its former ratings glory.
