Selena Gomez has decided to lengthen her Australia tour. The 21-year-old singer, who is in Australia for her 'Star Dance Tour' has told in an interview that she has a secret reason to extend her tour.

If you remember back in 2012, Selena Gomez has spent some romantic time in Australia with her ex-boyfriend Justin Bieber. So is Selena going to meet Justin Bieber secretly?

"I went on the road in Australia with my ex-boyfriend. I loved it. That's why I secretly wanted to extend this tour, to make sure I could go to Australia," Selena reveals to News.com.AU. "I didn't get to do much last time; I'm probably going to be a complete tourist this time around."

When Selena Gomez had come to Australia for a short trip with Bieber she had called their vacation magical. It was the time when Selena Gomez was head over heels for Bieber and the couple couldn't wait to go on romantic waterfront dates.

Selena broke-up with Justin Bieber last year and since then she is having hard time forgetting him. It has been reported by various sources that Selena Gomez misses Justin Bieber. So will she miss Justin during her trip to Australia?

Meanwhile, Justin Bieber premièred his new movie clip 'Believe 3D' on Good Morning America. In clip Bieber tells his fans about his relationship with Selena Gomez, the break-up and the highs and lows of his career.

"I could be going through a big argument, and I'm like, 'I'm about to go on stage right now.' And we were yelling...and like then I got to rise up on the toaster." He adds, "[Sometimes] I'm upset, and I don't want to have to smile," says Bieber in one of the Believe 3D snippets.

In all probability he is referring to Selena Gomez here.

So with Justin making a documentary about his break-up and Selena touring Australia to rekindle her romantic memories; is there a possibility of the two getting back together?
