Justin Bieber and Selena Gomez may be back together in real life, but they’re most definitely in this new mashup of their hits: his “As Long as You Love Me” and her “Come & Get It.”

A fan of the two who goes by Lucho Selenator posted a mashup of the two radio hits on SoundCloud … and it’s been getting a lot of love from fans.

Of course, Justin and Selena have rekindled their romance. As RyanSeacrest.com previously reported, the two shared a kiss backstage at the Billboard Music Awards on Sunday night — and it had the adverse effect on Taylor Swift, who made a face and stuck out her tongue.

In a new video, the twosome can be seen sharing a kiss backstage at the Billboard Music Awards on Sunday night.

The cute clip begins with Justin waiting backstage and he keeps looking down a hallway, as if he’s waiting for someone.

That special person turns out to be none other than Selena, who arrives backstage with BFF Taylor Swift. Justin walks up to her and she throws her arm around Justin as he gives her a kiss (just after the 1:00 mark).

Although the moment is sweet, Taylor didn’t seem to think so. Check out her funny “gross” face after she sees Justin and Selena smooch.

Justin and Selena fueled rekindled romance rumors on Saturday night when they caught a performance of LOVE by Cirque du Soleil at the Mirage. A source told E! News that the two “got close and comfortable in their seats while snacking on peanut M&Ms and Mike and Ikes candy.”

The Backstreet Boys member, who’s had his fair share of the spotlight at Bieber’s age, revealed to On Air with Ryan Seacrest: “I’ve been in that position before and you know what? Sommetimes you’ll make a mistake and sometimes you’ll come out on the other end. That’s just kind of like the luck of the draw. Stay healthy and just treat people good, you know what I mean?”

Backstreet Boys -- In a World Like This Tour

The long list of presenters, performers, and other special guests was revealed on Thursday … and there are tons of huge names.

And many of them will be on the stage together. Amongst the collaborations: Pitbull and Christina Aguilera on their hit “Feel This Moment,” Pitbull again with Jennifer Lopez for her new song “Live It Up,” Will.i.am and Justin Bieber for “#ThatPower,” and many more.

Other performers who will be rocking Las Vegas solo include Taylor Swift, Bruno Mars, Selena Gomez, The Band Perry, and Miguel.

The list of presenters is just as impressive. Handing out awards will be PSY, Ke$ha, Shania Twain, and Miley Cyrus, who has hinted that she will be making a big announcement about her upcoming album at the show.

The Billboard Music Awards, which will be hosted by Tracy Morgan, airs on Sunday, May 19 on ABC at 8 p.m. 

The 20-year-old Spring Breakers actress talked to In Style magazine about transitioning from music to acting, but Selena also revealed that her new album, “Stars Dance,” includes a song she wrote, called “Love Will Remember,” about Justin after the two faced a highly-publicized split last year.

“That’s the most personal track on the record, for sure,” she explains. “I think it’s a sweet way of releasing it. It’s not an aggressive approach to what people are probably expecting. I’m sure he’ll love it too.”

We definitely wonder what Justin will think of the song, especially after the two have officially reunited following reports that Selena flew to Norway to see him … and the release of this super cute photo that confirmed our suspicions.

Still, Selena told the mag that she’s looking for the real deal with future partners. “You have to have honesty when you’re living this lifestyle because of the distance imposed when working — you are separated so often. You have to be super-honest and open. That is key.”

On Sunday night, a male Belieber rushed the stage as the singer was performing “Believe” on a piano during a concert in Dubai.

In a video from the show, the young man can be seen running up behind Justin as he sits at the piano … but he didn’t get much time with the star.

Within seconds, security rushed the fan. As they took him down, the piano actually tipped over and crashed, but Justin, ever the professional, kept right on singing.

And he wasn’t bothered afterwards either. In fact, Justin retweeted a few fans who wrote about the crazy incident, including his guitarist Dan Kanter. “It wasn’t a prank,” he wrote. “Someone ran on stage during Believe and the piano got knocked off its platform. Everyone is fine. No need to worry!”

In a new interview with Elle UK, the 20-year-old former Hannah Montana star talks about how she tries to keep her private life from the public, starting with her Twitter feed, and revealed that she passed on some of that advice to Justin, 19.

“I noticed he was taking all these photos of people and doing a lot of s–t,” Miley tells the mag in its May issue, “and I just grabbed him and said, ‘Just take a snapshot in your brain of this moment, so you don’t forget.’ I don’t remember my Hannah Montana movie premiere – and my 3D movie trumped everyone’s at the box office – I don’t remember being there. All I remember from that night is that I stopped and got a strawberry milkshake beforehand. That’s all. It’s crazy. You think you’re in the present but you’re not.”

Selena Gomez Performs ‘Come & Get It’ at Radio Disney Music Awards

Despite it sounding like good advice, it doesn’t seem like Justin exactly took it. Last Friday, he posted a photo of himself with maybe on-again girlfriend Selena Gomez cuddling … but who can blame him, it was so cute!

Miley also gave a little insight into her relationship with fiancé Liam Hemsworth. “We have a house together and dogs,” said the “Ashtrays & Heartbreaks” singer. “It just seems right to be wearing this ring and to be committed. But we keep our relationship low-key and don’t talk about it any more.”
