Looks like things are getting hot and heavy between on-and-off couple Selena Gomez and Justin Bieber. According to a report by HollywoodLife.com, Selena Gomez had just spent $3 million on a stunning mansion and she wants Justin Bieber to move in with her. The Canadian pop star revealed to the public that he was moving out of California to find a new home. Maybe the plan after all is to bring him back to California?

The couple are getting serious about their relationship. After a nasty falling out in January, where the two sent vile messages to each other, Selena Gomez and Justin Bieber came out strong despite the strong disapproval from loved ones. Previously admitted for emotional trauma in a rehab facility, Selena Gomez' parents vehemently opposed the reunion of the two stars. The "I Knew You Were Trouble" singer Taylor Swift has also expressed her disapproval of the relationship.

But now, looks like only death can separate the two (and possibly some of Justin's womanizing ways). According to reports, the two are already on the verge of being engaged and getting married, although no official comment has been released by the two camps on the matter.

Could it be that Selena Gomez is trying to keep her man close to her so that she can spy on his every move?

"The real reason Selena bought that $3 million mansion in Calabasas is because she wants Justin to move in with her," an insider revealed to HollywoodLife. Com.

The 7,200 sq. ft abode is located (coincidentally) in Calabasas, California also the exact location of Justin Bieber's previous mansion. Bieber moved out from his Calabasas abode after falling out with some of his neighbors due to issues on trespassing and egg-pelting incidents.

"Justin is actually considering it and for now will stay with Selena whenever he's in town. Before Selena purchased the house, she consulted with Justin and they both agreed on the one in Calabasas," the insider to Hollywood.Life.com further revealed.

Is Selena Gomez about to tie the knot with Justin Bieber? The ring on Selena Gomez' hands is the answer to it all.
