On Saturday, Selena Gomez was seen leaving a Pilates studio in Los Angeles while rocking a stunning appearance.

The singer, 25, flashed some skin while sporting a black Puma sports bra with a crisscrossed back and light gray sweatpants tucked into Puma underwear that protruded above the waist. Gomez represents the sportswear company as a spokesmodel.

She had a kidney transplant this past summer because of her lupus. In September, she made the announcement. Back then, E! News was informed that Gomez was “working with multiple doctors and nutritionists to get her health back on track” and was “slowly” returning to her regular exercise regimen, which included Pilates, yoga, and light weight training.
