'It's so surreal,' the singer/producer says of performing and being nominated for Sunday's show.By Peter de Saint Phalle, with reporting by Jayson Rodriguez Bruno Mars Photo: MTV News It's no secret that this has been a big summer for Bruno Mars. Whether he's producing profanity-laced records with Cee-Lo Green, collaborating with B.o.B and Travie McCoy or touring to promote his debut EP It's Better If You Don't Understand and upcoming LP, Doo-Wops & Hooligans, this producer-turned-rock/soul singer is popping up everywhere. This week alone, Mars is hitting our screens with the premiere of his "Just the Way You Are" video and with a performance at Sunday's MTV Video Music Awards. "It's all happening so fast," Mars told MTV News last month, when reflecting on his successes in the past months.
