Despite posting a couple of throwback photos of ex Selena Gomez on Instagram, Justin Bieber appears ready to move on. Yesterday, the 21-year-old asked fans to help him find a mystery girl by re-posting a picture of the stunning brunette on Instagram. "Omg who is this!!" he wrote.

Bielebers quickly came to his rescue in the comment section and, judging by a majority of the replies, she is an Instagram user who goes by the name Cindy Kimberly. Bieber has yet to comment or thank his fans for identifying the girl, reported Us Weekly.

Despite the series of photos Bieber posted of him and Gomez, 23, and even after the two were spotted together at a hotel last month, sources confirmed they are not back together. "They care about each other and miss each other," a source told People. "But they're not getting back together."

Gomez sparked romance rumors with One Direction's Niall Horan after they were seen at an amusement park together this past weekend. They were also seen dancing together, kissing and hugging following their performances at 102.7 KISSFM's Jingle Ball, insiders told E! News. Neither have confirmed the dating rumors, though.

 Omg who is this!!
