Jessica Biel has been having a busy week. A day after news broke that the actress will executive produce and star in the pilot for new TV drama The Sinner, Justin Timberlake's other half was seen hitting a yoga class in Studio City, California, and her simple, chic athleisure look made us do a double take.

The mom-of-one, who celebrated son Silas's first birthday in April, looked radiant and fresh-faced in an all-black ensemble after her yoga class on Thursday. The 34-year-old opted to get in a workout in a form-fitting black tank top, which she paired with skintight black leggings that hit just above her ankles. Black-and-gray kicks finished off her simple but flattering look.

While Biel might have picked basic athletic pieces for her yoga session, she was not shy about accessorizing the look: The actress added two layers of thin gold necklaces with round pendants, a large slouchy brown shoulder bag, and oversize sunglasses to protect her eyes from the L.A. sun. Lastly, the star pulled her ombré strands back in a high ponytail for her workout.
