Justin Bieber and Selena Gomez have been dating for more than a year, but a pal close to the couple exclusively tells Breaking Celebrity News that the pair is on the rocks and they regularly come close to splitting.

Despite being photographed at Justin's October 20 concert in Minnesota, the once inseparable couple have not been pictured together in quite sometime and the insider blames jealousy and over-dramatic antics.

"They both can be very jealous," the pal told Breaking Celebrity News.

"Selena can be so dramatic about Justin's exes, who aren't even in her league! They both engage in really petty arguments and it's killing their relationship."

Although the two have been labeled as a young Hollywood power couple, the source says a breakup is imminent — but it's Justin that just can't let go.

"They 'almost' break up regularly," the insider said.
