Fergie is on the verge of leaving the Black Eyed Peas permanently as tension in the band has become intolerable for her, RadarOnline.com has learned exclusively.

The band has a full tour schedule for the summer and is planning a tour for early 2011. But Fergie won’t commit for that part of the tour, we learned, and the reason is she’s talking about leaving the band for good.

Fergie can’t stand Will.I.Am and that is one of the main reasons she wants to leave the band, a source close to them told RadarOnline.com exclusively. The other reason is she’s decided she wants to have a baby!

“Fergie is saying she wants out of the band and the second half of the tour isn’t confirmed for early next year,” the source said.

“Things have gotten really bad with Will.i.Am. And it’s not just Fergie who is clashing with him. So is the rest of the band. His ego is out of control.

“Fergie just wants to get away from the whole thing.”

Fergie has kept the news so secret that very few people know and she is not ready to make the announcement right now, the source told RadarOnlne.com.

"You see people coming and they strip at your bachelor party but I want her to strip at my bachelorette party. She's hot, I love her. She's just the coolest chick and I want all of her clothes," Katy Perry gushed.

The match made in ABC heaven just months ago, have ended their engagement, Pavelka's rep confirmed, bumping the total of failed Bachelor couplings to 13 (if you don't count Jason Mesnick and Melissa Rycroft).
