Selena Gomez is back with Justin Bieber but this time the Texan beauty wants Justin to make a formal proposal to her, various media reports suggest. The 21-year-old songstress flew down to Canada to be with the "Baby" singer but according to various inside sources Selena wants a "formal commitment" from Justin this time.

"This time around, Selena wants some formal commitment from Justin, which of course Justin has promised but has yet to deliver," a source close to Selena Gomez revealed to Hollywoodlife.com.

"Selena is convinced that she and Justin will be together forever despite their roller coaster history. If Justin proposed, Selena would say yes in a heart beat," the source added, according to Web site.

Selena flew to Canada to be with Justin and his family at a time with his dad was celebrating his 40th birthday with the other members of the family. Jeremy Bieber also started following Selena Gomez on Instagram at the same time. Justin's family is happy to see them back together but at the same time they are also worried about the on and off pair.

According to other gossip Web site Oceanup.com, Justin Bieber and Selena Gomez are also spending lot of intimate moments together (read having sex) and this is making Justin's parents worried.

"They're a little freaked out by how fast [Justin Bieber] and [Selena Gomez] are moving, but they're just chalking it up to young love, for now," a source close to Jelena told the Web site.

Justin Bieber and Selena Gomez are in an incredibly inseparable relationship, it seems. The singing couple are reportedly back together and have watched a movie "The Lincoln Lawyer" together, various reports from Entertainmentwise.com magazine are suggesting. Justin Bieber also posted a picture of his bedroom where he is seen lying down watching the movie and there seems to be a pair of feminine feet with socks where Justin is seen keeping his head. Check out the picture here.

The couple had reportedly celebrated some good time together in Canada sometime back and it was accidently confirmed by one of their family friends on Twitter. But the moment she realized her mistake, she deleted the tweet, Entertainmentwise.com reports.

However, this time around it seems Justin and Selena are back for good as Selena has reportedly been posting positive messages on her Instagram page and has deleted all negativity from her life.
