A quick search online for Black Eyed Peas today gets you a whole bunch of rumors. Some say the band is breaking up due to the ego of Will.i.am, some say the band is taking an indefinite break to focus on solo careers, some say Fergie has left the band to have a baby...
What is the truth? Who knows, at this point. Fergie told a recent crowd in England that the show would be the last they play for a long time... which leans toward the indefinite hiatus theory.
At this point, I'd say it's anybody's guess what the future holds. They've taken a break before, so this wouldn't be anything new.
