Selena Gomez is showing off a healthy and fit body in a new ad campaign.

The 21-year-old singer/actress was spotted on set of her new Adidas NEO campaign shoot in New York City on March 11, showing off her toned abs and stylish street-casual looks.

Gomez has been a spokesmodel for the youth apparel line since 2013. In addition to starring in print and commercial ads for the brand, Gomez has contributed designs for the line's various sneakers, clothing and accessories.

Days prior to her Adidas ad shoot, Gomez performed two festival shows in Texas, her first time performing since canceling the Australian leg of her "Stars Dance Tour" and reports of a rehab stint in January 2014. The two shows consisted of songs Gomez performed as part of the "Stars Dance Tour," including "Come & Get It," "Slow Down" and "Who Says."

In addition to Gomez's professional triumphs, news of her personal life has been making headlines, particular her relationship with singer Justin Bieber. When brought on camera during a recent deposition, Bieber refused to answer questions about Gomez, saying, "Do not ask me about her again."

The two, who have not confirmed whether or not they are once again dating, were also recently seen in a series of Instagram videos dancing in a studio to the John Legend song "Ordinary People," according to Us Weekly. The videos have since been removed from Bieber's official Instagram profile.
