Selena Gomez's new song "Rule the World" has just become available on the internet. Although it's uncertain yet whether it was indeed leaked or actually released by the 20-year-old singer herself, what's clear is that it's a new break-up anthem, supposedly about her ex-boyfriend Justin Bieber. The lyrics of the new song, seemingly dissing her former beau, can be considered another blow to The Biebs' already tough week in his "Believe" tour.

"Our love was made to rule the world / You came and broke the perfect girl," Gomez sings as she seems to refer to their doomed romance. The Disney-bred star wears her heart on her sleeve with the words, "Though we were never lovers in the end / I try to tell myself this pain would go away / Just go away."

Although it may be a diss at Bieber, the words used are definitely way better than those in Dustin Tavella's "Everybody Knows" track which Gomez, along with four other girl friends strutted to when they recently recorded a dance video. The clip had the pretty insulting words, "Everybody knows...your boyfriend is a d***hebag."

Whether it's the first single or a follow-up to "Come and Get It", as one source from Gomez' camp claims, what's evident is it will be a good addition to the pop star's forthcoming new album, said to be released in April. Even the Wednesday break-out for the new single is in line with Gomez's announcement back in January that she will drop a new single by March.
