Life & Style can reveal that while in Miami to co-host the Y100 Jingle Ball on Dec. 8, Justin Bieber secretly met up with Victoria's Secret model Barbara Palvin — the same girl he was spotted getting cozy with at the Victoria's Secret fashion show in November while he and girlfriend Selena Gomez were on a break.

"Justin and Barbara were together in Miami," a friend of Justin's confirms in the new issue of Life & Style, on stands now. "They aren't being bashful about hanging out and getting closer."

Barbara, 19, seems more than happy to let the world know she's been spending more time with Justin, posting pictures of herself in front of the 18-year-old's tour bus and wearing his concert T-shirts in plain view.

As Life & Style previously reported, the Wizards of Waverly Place star pulled the plug on their two-year romance in October as reports of his wandering eye surfaced, but she agreed to take him back if he promised to be faithful. "Selena laid down the law about what Justin must do to make her happy," says another pal. "She was very specific and told him if he messes up, it will be over."
