The Biebs was photographed with a gal pal on Space Mountain on August 6. They were joined by his BFF Lil Za. He had a mystery chick with him, too.
This girl is probably just another one of Justin's hookups. He was spotted getting cozy with a model in Ibiza less than a week ago, and reportedly left a party with Kendall Jenner around that time, too.
One girl he hasn't been seen with in awhile is his ex Selena Gomez. He took her to Disneyland on a date back in 2012.
Do you think Bieber's Disney mystery girl will be his next Selena? Or is she just another one of his random hangouts?
