Bruno Mars - "Treasure"
Miley Cyrus - "We Can't Stop"
Selena Gomez - "Slow Down"
Ciara & Nicki Minaj - "I'm Out"
Pharrel will probably perform with Daft Punk and/or Robin Thicke
It would be awesome if Lady Gaga performs her new single, but I'm not expecting anything right now.
YG better send 2NE1 this year like they did with PSY last year
Just get Gaga and Beyoncé on the show and it's a hit. I'm expecting to see Beyoncé attend the award show because it is held at Barclays Center because it's the home of the Brooklyn Nets and Jay is a member of the ownership of that name. So it would only be logical for Jay to attend along with Beyoncé. Now it would be PERFECT if Beyoncé would perform at the show but I highly doubt that.
Macklemore will DEFINITELY be there.
JT and Jay-Z is another for sure. His Part 2 album is about to come out.
Ellie Goulding. I can see her being there.
P!nk
Robin Thicke.
Lady Gaga for sure.
It doesn't sound well rounded though. I can't think of anyone else.
