Pop star Joe Jonas is single again after reportedly calling time on his short-lived romance with model Jessica Serfaty.

The singer, 26, was photographed kissing the former America's Next Top Model contestant during a skiing trip to Mammoth Lakes, California in January (16).

It was subsequently revealed the couple had met through a mutual friend and had spent the festive holidays in Las Vegas together.

However, it appears Joe's chemistry with the 24-year-old Arkansas native has since fizzled out.

"They're not even talking anymore," a source tells People.com. "That (relationship) was made into a bigger deal than it was."

The brief love affair was Joe's first following his split from another model, Gigi Hadid, last autumn (15).

She has since also moved on and is now dating former One Direction star Zayn Malik. The young couple was first linked in November (15), a few months after Zayn parted ways with his ex-fiancee, Perrie Edwards.

The Brit only recently confirmed the romance in a radio interview, after cavorting with Gigi in the steamy video for his debut solo single, Pillowtalk.

Asked by a fan if it was "cool to have (his) girlfriend in the video," the singer told Zach Sang & the Gang, "Uh, yeah. That was cool. it was something different. We enjoyed it. It was fun."

"No one easier to make out with than your own girlfriend, right?" a co-host followed up, to which Zayn simply responded, "Exactly".

Ironically, Gigi was also involved with Joe's video for his band DNCE's Cake By the Ocean promo, which served as her directorial debut.
