B.o.B took to Twitter last night to reveal news that his Lil Wayne-assisted single, "Strange Clouds," has sold its one-millionth copy. Congratulations to Bobby Ray!

However, the "Airplanes" rapper also announced that his sophomore disc, Strange Clouds, would not be coming out on March 13 as it was originally planned, but on May 1. 

"Sorry for the wait but I promise it's a phenomenal album...#StrangeClouds," Bobby Ray tweeted.

B.o.B will release his next single, "So Good," on Feb.14, Valentine's Day.
