Justin Bieber New Girlfriend? [PHOTOS]: 'Believe' Singer Spotted with Pretty 'Mystery Girl' in Disneyland, Chills at Miley Cyrus' Pad, Sparks Collaboration Rumors

Although spotted "flirting" numerous times, Justin Bieber and Selena Gomez officially broke up months ago. Since then, rumors surrounding Bieber's "new girlfriend" have taken the web by storm. Over the weekend, the "Believe" pop star was spotted chilling with his bros in Disneyland... he also "cuddled up" with a mystery girl on a roller coaster ride. The identity of this young woman still remains a mystery... but we have some photos of the beauty and her flirty interactions with the Biebs to prove it! Is Jelena over for good?

On Sunday (June 9), 19-year-old Bieber took time off from his grueling schedule to have some fun in Disneyland. Bieber donned a hat, sunglasses, and grey hoodie... it didn't look like he was in the mood to interact with fans, although it appears he had a pretty good time with friends.

"[He] was surrounded by a lot of security. Half were like his personal security and the other half were from the theme park," an insider tells E! News. "He walked towards Tower of Terror and went behind a gate so nobody could see him... He wouldn't let anyone talk to him and he was walking pretty fast."

But the Biebs was spotted comforting a gorgeous gal on a roller coaster ride. Check out the exclusive photos here.

Maybe she's just a good friend, perhaps the two teens were randomly seated with one another... still, the photos have since gone viral. Considering Bieber rarely acknowleged any of his other fans during the amusement park outting, it appears this young lady got some extra special attention! Here's a Twitpic of the unidentified "mystery girl."

Potential girlfriend material?
