What a difference a year makes!
"Jersey Shore" star Deena Cortese just tweeted a photo of her red carpet look for this year's MTV Video Music Awards -- and she looks gorgeous.
Wearing a tight black and silver mini, sporting some luscious dark locks and flaunting her fit figure, Deena is a whole different meatball!
Take a look at how she looked at last year's event (left), where she had crazy green contacts, a wild dirty blonde 'do and a crazy rainbow dress. How are these even the same girl?
Deena's been making a lot of changes in the past year, not only losing weight and dying her hair, but also getting new veneers.
Check out her year-long transformation in the gallery above -- and be sure to go to toofab.com to see all the latest from the 2012 MTV Video Music Awards.
