Weezer have posted a small statement on their website in regards to reports stating the band has broken up:

this PSA has been brought to you by the fine guacamole dip at Scott Shriner's house, co-sponsored by a ring of fine cheese, and a dish of fresh figs from the back yard. Now please, take those "weezer split?" headlines and place them firmly into the "Don't believe the hype" bin. And have yourself a fine afternoon now.

In an interview with MTV last month, Rivers stated that "for the moment" the band was done.
