Sammi Sweetheart may be a professional guidette, but believe it or not, the girly reality starlet, who's known for her fake nails and hair extensions, used to rock cleats and shin guards on the regular.

The Jersey Shore star took to Twitter today (January 10) to show off her sportier side with a flashback photo of herself looking super intense on the field. Sammi wrote, "#tbt soccer days lol."

How did Sammi's soccer days affect her physique?

In an interview with the Sun-Sentinel from last winter, Sammi said, “When I was playing soccer [during Season 1], I was a lot more thicker. Was more muscular. I'm not doing the hard college workout now that I used to. I think I'm a decent size, just not crazy muscles.”
