Vanessa Hudgens & Austin Butler's Studio A Fitness Session

Trying to keep a low profile, Vanessa Hudgens kept her head down as she made her way into Studio A Gym in Toluca Lake, California on Thursday (July 26).

Carrying a white towel and a large jug of colored liquids, the "Sucker Punch" babe was joined by boyfriend Austin Butler as she strutted in the building through a back entrance wearing some brightly laced tennis shoes, cropped black exercise pants and grey zip-up hoodie, of which she pulled over her olive hat.

Although Vanessa nervously chewed on her nails as she avoided the cameras, the actress recently promoted nail polish by Butter London while admitting on her blog, "I love nail polish and paintin’ my nails. The darker colors that shimmer are the best!"

On the business front, the 23-year-old is currently working on the 2013 film "Machete Kills" which follows the story of Machete battling his way through Mexico after being recruited by the U.S. government to take down an arms dealer who looks to launch a weapon into space.
