We expect them to be sitting next to each other at tonight's 2013 Billboard Music Awards, but the day before, there is no question that Justin Bieber and Selena Gomez were once again very used to being up close and personal with their seating arrangements!
The notoriously on-again/off-again couple, who are expected to appear together at tonight's ceremony - held at the MGM Grand in Las Vegas, got a head start on their Sin City trip a night early on Saturday, when they took in the LOVE by Cirque du Soleil performance at the Mirage!
According to eyewitnesses:

Well, we think we finally put all those "are they?" or "aren't they?" rumors to rest, folks!
Because it appears that despite her recent denial, Selena Gomez is TOTALLY back together with Justin Bieber!
If you want to go by their upcoming seating arrangements at the 2013 Billboard Music Awards, of course!
That's right! These two are

We see you, doll!
Selena Gomez has tried plenty hard to hide her adorbzie face from the paparazzi, but there's just no denying it!
And she certainly shouldn't be hiding that lovely face anyway. Would you?!
Selenita was spotted heading to lunch at Sushi Dan after her dance rehearsal, but she was looking far more open to being photographed than we saw when she was leaving the dance studio.
Although she did TRY to hide out behind a scarf (below), it seems it just didn't work and Selena gave in!
Maybe she realized she was about to have bigger things to hide…
…like her rumored clubbing night out with Justin Bieber!

Sooo, they're ON again?!
These two are getting to be worse than Chris Brown and Rihanna!
Seriously, their Facebook relationship statuses would be beyond annoying right now if they were regular people who actually did that shizz.
Selena Gomez might be proclaiming her singleness from rooftops, but her actions are telling a different story. And that story involves a leading man named Justin Bieber!
Although we were almost totes convinced their little romance was over, they've thrown us for another loop with a date night out to da club!
It seems the former tween twosome was spotted out at

Could this sweet gesture be enough to win back Selena Gomez's heart?!
Selena and Justin Bieber are BOTH scheduled to perform at this this year's Billboard Music Awards, but JB's interesting song choice for the show — an upbeat love song titled Take You — has us speculating…
Is he trying to seduce Selenita with a romantic serenade?!
The tune is an odd pick for the performance seeing as it's not a single off of Believe (at least not yet) nor has it garnered a lot of buzz.
Plus, even though Selena was recently spotted sneaking out of JB's house, she's also maintaining she's single…
So could this be Justin's plan to persuade the unsure Come and Get It singer to, well, come and get some Bieber action?!
Hmmmm!
We are VERY curious to see Justin's performance, and obviously, Selena's reaction! Draammmmaa!

We all knew from Demi Lovato's new song Warrior - and the tattoo of the lyrics she recently had inked onto her skin - that she does not mess around when it comes to being a badass, but this is seriously HARDCORE…even for her!
The pop sensation recently sat down for an interview with MTV News, during which she revealed that although she has to have her tonsils removed over the summer before beginning her duties on the judges panel of X Factor, she does NOT plan on taking any chances with her past addiction struggles, and will be undergoing the surgery WITHOUT the help of painkillers!
And this won't even be the first time!
That's right! She had her wisdom teeth removed AND endured that painful-looking foot injury au naturale, folks!
We couldn't be more proud of her for choosing to honor her sobriety and not even risking the chance of slipping up by taking a much more painful, uncomfortable alternative! But as we all know, the right way isn't always the easy way!
Ch-ch-check out the full interview for more, as well as what else she has to say about her friendship with Selena Gomez (above)!
