Many people are wondering what the real reason is for the Selena Gomez Justin Bieber break up. There were rumors that a third party was involved and it could be Kendall Jenner because the two were seen hanging out at a party a few days ago.

However, a source revealed the real reason why the on-again off-again couple ended their relationship. When the two reunited last month, everything seems to be going smooth and they even went to several romantic getaways together. Suddenly, reports came out that the lovebirds have broken up again.

The 22-year old actress is ready to get married this time to the 20-year singer, but the question is if he is ready to settle down with her. A source revealed to Hollywood Life the real reason for the Selena Gomez Justin Bieber break up and it's all about commitment. The Canadian pop star allegedly isn't ready to get hitched.

The insider said, "There is so much back and forth in their relationship that even if Justin proposed to Selena, which isn't currently an option, he would never go through with it." Their source added, "They would fight on wedding details or something else that would ruin things again and they would have more fights. At the end of the day, he will only marry her if he accidentally impregnates her."

I guess the "Behaving Badly" actress already know now what she can do to get the "Baby" hitmaker from marrying her. Actually, there have been rumors in the past that she got pregnant and had a miscarriage.

Reports came out a few weeks ago that the young couple are having reckless sex and if a baby comes along because of it, then marriage may follow. A source also revealed to OK! Magazine, "The two stars are determined to leave their once bright futures almost entirely up to chance. Despite the fact that neither Selena nor Justin seem even remotely ready to be a parent, the pair are knowingly risking that outcome every single time they get together."

It isn't surprising that the two don't practice safe sex since they are both young and carefree; so there's also a big chance that the pregnancy rumors were true. What do you think is the real reason behind the Selena Gomez Justin Bieber break up? And do you see them getting back together again?
