*Surprising hit “Nothin’ on You” by B.o.B has scratched its way to the #2 spot on Billboard and iTune charts since its release in February.

The rapper is simply amazed at the song’s success. He never expected the song to catch on like it did.

“We really didn’t expect it to have the dramatic impact it had, nor how fast it happened,” B.o.B told MTV. “Me and my managers, B. Rich and TJ, we still look at each other speechless. We always aim to be successful. But when the byproduct exceeds your expectations – when usually you barely make the basket with what you want – the gratitude is through the roof. It’s literally a dream come true.”

He says the song is sincere and it speaks to the hearts of women, bringing smiles to the masses.

Bruno Mars worked his magic, singing the vocals and producing the track. The pair calls this hit their “golden egg.” Though they expected the song to do well, they never imagined it would be knocking on the door of #1.
