The Billboard Music Awards are getting bigger and bigger. With the performance lineup already including Taylor Swift, Justin Bieber, Bruno Mars and a handful of others, they haven't stopped there. Some heavy hitters have just been added to the list.

Selena Gomez, Macklemore and Ryan Lewis, Christina Aguilera and Pitbull have been confirmed to hit the stage on May 19th in Las Vegas. As fantastic as this is, we’re left with one simple question: how is ithis going to play out for Justin and Selena? Come on, you know you were wondering, too...

Since the two are practically back together (or just really, really missed each other) seeing as Selena flew all the way to Norway to be with him, does this mean the two will show up together? Are they going to sit together? Answer: likely not, since they’re trying to keep it on the DL... which they’re not doing the best job at, by the way. But cheering each other on during their performances is a possibility.

The Billboard Awards nominees were announced earlier this week, giving everyone a nice reminder of who kicked ass this year on the charts. For a refresher, Taylor, fun. and Maroon 5 lead the nominations, each snagging 11 while Rihanna comes in second with 10.

And the least surprising nominees are all in the Top Artist of the Year category, which include Taylor, Maroon 5, Justin, Rihanna and One Direction. Yeah, we saw this coming since they’re pretty much all we've talked about in the past year.
