Selena Gomez is dating Justin Bieber on a 'Trial Period' to avoid a broken heart.

Justin Bieber and Selena Gomez have kept gossip columns busy wondering whether they are an item or not for the past few weeks, but now insiders say the ex couple are indeed back together but for a "trial period only".

“Justin and Selena are dating but they are taking things slow,” a source has revealed.
“Coming back together now, the couple has years of experience and they're treating the relationship more maturely this time around. They now know what the stakes are.”

The pair first aroused suspicion that they were dating last month when Spring Breakers star Selena apparently joined Justin in Oslo while he was performing in Europe for his Believe World tour.

Eyewitnesses were quick to reveal that the pair where seen out and about looking mighty loved-up. However, despite the rumoured reunion, sources have revealed that Selena is keeping her heart well guarded and is taking things slow so she’s not left broken hearted.

"Selena is keeping her heart from being broken, so she is definitely looking at this as a trial period in their relationship. She's definitely taking [baby] steps back," they said.

"When they first started to date, it was amazing but they were too young and it was too much. They didn't even know what love was and she got all mixed up."

One person who might not be happy with Selena's rekindled romance will be BF Taylor Swift. The country singer apparently made her feelings clear when she stuck her tongue after her good pal and Justin embraced each other with a kiss at the Billboard Awards this month.

So, do you think that the relationship will last? Or is it just another fling. We wanna know..
