The 'Come & Get It' singer was spotted on the set of an Adidas NEO commercial in Soho on Tuesday (11 March), after jetting in from her native Texas, where she'd been hanging out with ex-boyfriend Justin Bieber.
Selena, 21, wore a few different outfits for the shoot. Making the most of a day of spring temperatures in New York, she donned a cropped jumper for one set of shots, and wore a strapless blue top in another.
Selena was filming her advert at High Line park.
The former Wizards of Waverly Place actress was signed by Adidas NEO as a style icon and designer back in 2012.
At the time, she said: "It is a great partnership for me because NEO really cares about style and having fun with fashion and allowing you to be yourself. This is something that's always been important to me and is important to my fans, too: knowing they can express themselves through wearing whatever clothes they want and feel good about themselves."
Selena added: "I am really enjoying being involved with the design process and NEO is letting me have fun with this. I get to wear the clothes first and have a voice and an opinion and I can't wait to see the results of our new collection. I'm excited that it also allows my fans to be involved and they can come with me on this journey."
Other celebrity ambassadors for Adidas NEO label include Tom Daley and, interestingly, Selena's ex Justin… or on-again boyfriend Justin, according to rumours.
Selena and Justin split in January after an on-off relationship going back to 2011, but over the weekend they were spotted together in Texas, fuelling rumours of reconciliation.
Justin, 20, further fuelled the speculation himself by Instagramming a sexy video of him and Selena dancing together at a studio, although it was later deleted.
And, adding confusion to matters, Selena has also been enjoying dates with One Direction star Niall Horan, sparking a celebrity love triangle. Check out the new issue of Reveal magazine, in shops now, for all the details on what's happening.
