Did Justin Bieber just break up a celebrity couple?

G.I. Joe Has Officially Come To An End

In early January, Joe Jonas went public with America's Next Top Model contestant Jessica Serfaty, and weeks later, she was spotted with Bieber, which seemingly prompting a breakup announcement earlier today. But was Bieber to blame?

"They're not even talking anymore," a source told PEOPLE Magazine of the former pair on Monday. "That was made into a bigger deal than it was."

Was Joe Jonas 'Blindsided' By Gigi Hadid's Romance With Zayn Malik?

In January, Jonas and Serfaty were spotted kissing during a ski trip to Mammoth Lakes, California, and at the time, a source claimed they "dating," but noted that it was "nothing serious yet."

The couple was also believed to have spent the holidays together after meeting through a mutual friend in Las Vegas.

Although it was never revealed whether or not Bieber and Serfaty were an item, they haven't been spotted together since they were photographed leaving The Nice Guy in West Hollywood, Calif. together last week. And since then, Bieber appears to have rekindled his romance with Hailey Baldwin.

Over the past few months, Bieber has been linked to a number of women, including Serfaty, Baldwin, Kourtney Kardashian, Sarah Jeffery and Selena Gomez, but judging by his recent trip to San Francisco with Baldwin, it seems she is the one who has his attention -- at least for now.
