Love triangle? Selena Gomez and Justin Bieber might of pulled the plug on their on-again-off-again relationship awhile back, but the "Revival" singer is reportedly wanting to get him back despite his hot fling with Kourtney Kardashian!

Since the tragic death of Selena's friend, Christine Grimmie, in mid June, the singer has been "re-evaluating life," a source told In Touch magazine. "She realized life is short, so she called him and told him she loved him."

However, it might be a little too late now! "Justin explained that he is quietly seeing Kourtney Kardashian again," the source revealed.

"They've been so careful that some of Justin's team don't even know they're together," the insider dished.
