How have we known Sammi for six seasons of Jersey Shore and not gotten acquainted with her borderline twinsie sister, Nikki Giancola?

Aside from having similar features, the Giancola girls seem to be passionate about the same things too. While Miss Sweetheart launched her own line of workout gear called Sexy Sweetheart, her sis is a mini business mogul herself, with her own workout company called Fixx Me Fitness.

Now all we need to know is if Nikki's dating a guy like Ronniepsh, who are we kidding, RonRon is one-of-a-kind. So do you think these iron-pumping brunette sisters look alike? Vote in our poll below!
