Vanessa Hudgens Flaunts Rock Hard Abs And Sports Bra In Sexy Selfie Pic! [Instagram Photo]

After heading off to the gym, actress/singer Vanessa Hudgens takes a self-portrait to show off the progress of her training. In her workout gear, the Spring Breakers starlet looks in great shape after spending many hours doing Pilates in the exercise room.

Notice the Bandslam singer placing her hand on top of her pouty lips, as if in a self-mocking tone. The fitness guru is actually surprised at how toned and fit her body really looks. Everyone can check out her extravagant belly piercing, her tight sports bra, and her rock hard abs all in one shot.

I'm surprised the Thirteen actress didn't break a single nail during her work-out session. Check out the well-manicured talons on her fingertips. Those fingernails look so sharp; they might actually scratch your eyes out.

We have seen Hudgens as an action star, previously in Journey 2: The Mysterious Island and Sucker Punch. The audience won't believe you're a tough guy if you don't act the part. In Sucker Punch, the role of Blondie asked the hard-working thespian to run many laps, roll around on the ground, and get pulled around by wires.

The High School Musical star writes beside her photo, "Oh snap! Hard work paying off! #abs #fitnessfreak#healthylife #stayfit #hustlin"
