Sienna Miller Plays With Pilates

British actress Sienna Miller wears a bright red tanktop to her Pilates class in Hollywood on Monday.

Sienna‘s pilates pal helped her to her car as they made their way through photographers.

The 26-year-old is currently dating Brothers & Sisters star Balthazar Getty and will begin filming Sherlock Holmes opposite Robert Downey Jr. next month.

After being photographed with Balthazar numerous times in the past few weeks, the pair have limited their public appearances as of late.
