New York, Dec 13 (IANS): After setting the record straight on rumours saying that she's dating singer Niall Horan, pop star Selena Gomez was spotted cosying up to her ex-boyfriend Zedd here.

The "Hands to myself" hitmaker was pictured kissing Zedd after they performed the Russian-German DJ's "I want you to know" together at the Z-100 Jingle Ball concert here on Friday, reports aceshowbiz.com.

The 23-year-old singer was photographed planting a kiss on Zedd's cheek and circling her arms around his neck.

Zedd, meanwhile, was smiling at the camera as he circled his arms around Gomez's body. Both of them looked matching in black outfits.

As previously reported, they remain on good terms following their split.

While it's unclear whether or not Gomez and Zedd are getting back together, the 26-year-old DJ posted on Instagram an image of them getting cosy at the same venue.

"Reunion with my favourite lil Mexican taco to perform#IWantYouToKnow tonight at Madison Square Garden," he wrote alongside the image.
