Justin Bieber and Selena Gomez have been dating for more than a year, but a pal close to the couple exclusively tells RadarOnline.com 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 RadarOnline.com.
"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.
"But it's a case of first love for Justin so he can't even imagine being without her."
Selena, 20, and Justin, 18, officially emerged as a couple when they attended the Vanity Fair Oscar party hand-in-hand on February 27, 2011 even though they'd been photographed together in the months leading up to that.
