When Selena Gomez sang about the heart wanting what it wants, you've been pretty sure that she's not over her ex, Justin Bieber.

And it looks like things are looking up for Sel's heart because there have been reports that she's been seen with her former beau at the Montage Hote in Beverly Hills over the weekend.

This prompted a lot of fans to go on a frenzy, and making "Justin and Selena" a trending topic on Twitter.

So what's up with her and the Biebs?

According to Perez Hilton and The Hollywood Life, the on-again-off-again pair was seen relaxing by the hotel pool with friends and family.

A photo showed a shirtless Bieber strolling into th ehotel with a towel wrapped around his neck and donning baby blue trunks. Selena was right behind him in a navy and white bikini underneath a black shirt and her head up in a ponytail.

There were even reports about the couple engaging in public displays of affection by the pool, but no photos have been published to prove these claims.

Photographs showed that Selena and Justin are comfortable in each other's company, which surprised many of their fans as recent reports from Inquisitr, among other websites, believed the pair to be estranged since their breakup in September.

The Gomez-Bieber saga has had fans divided, with many of them claiming to be strongly either for or against the couple.

Even celebrities have something to say about the on-again-off-again relationship,including Selena's famous BFF, Taylor Swift.

An insider for Hollywood Life said that Tay is not happy about the reunion, and is in fact "full of disappointment" in the matter. However, she is done trying to make Selena see how bad Justin is for her.

The insider said, "She is worried about her tour stop tonight but has heard that [Justin and Selena] got together and she gave the reaction that was basically full of disappointment. People around her are saying Taylor is showing a 'what the f-k!?' type attitude."

"Taylor is not over her friendship with Selena, but she is over trying to convince Selena that Justin is awful," the insider added.

While it looks like Taylor and Selena will survive their friendship, it looks like Taylor's strong dislike for her relationship with Justin is creating a gap between the two friends.

This seems to be the reason why Taylor has been absent from Selena's events lately.

The source shared, "Nobody wants the friend to go against everything you say to get the invites for fun when it's going to be drama and babysitting the whole time."

Do you think this next installment of the Selena and Justin drama is going to last, or will things never work out between these two?
