Justin Bieber and Selena Gomez have split.

The romance, that's been on the rocks for the last several weeks, ended late last month, according to several sources.

"Because of their crazy schedules, it was getting harder and harder to maintain a relationship," a source told E!

The Biebs, 18, and 20-year-old Selena have been dating almost two years -- an eternity for teens in Hollywood. But on Thursday night he was spotted with Victoria's Secret model Barbara Palvin, 19, seeing The Lion King on Broadway.
