Back in September, we told you that JWOWW was working on quitting her bad habit of smoking, but did it work?

It seems like our girl is done for good with cigarettes of all kinds. The Jersey Shore star tweeted:

We’re glad that she’s taking care of her amazing body and staying healthy — she has plenty of wedding planning to do with fiancé, Roger, after all!

And now she’s off to Vegas with her boo! Hopefully she won’t pick up another addicting habit, like gambling, there...

Are you surprised that Jenni quit smoking? Sound off below!
