After series of pictures of the duo spending time together circulated online, there were speculations that the two may reconcile as lovers, reported People magazine.
"They care about each other and miss each other, but they're not getting back together right now," a source said.
Last week, Justin Bieber, 21, serenaded ex-girlfriend Selena Gomez, 23, at a hotel lobby bar, and the former couple were photographed strolling together later.
Gomez, who performed her latest single "Same Old Love" at the American Music Awards (AMAs) also attended "Baby" hitmaker's after party.
