Los Angeles musician Kim Shattuck was called in to replace Kim Deal as bassist for alt-rock legends Pixies just four months ago, but her time with the band is through already and she's pretty disappointed about it.

Shattuck, who has in the past been best known for her work in pop punk band The Muffs, took to twitter and Facebook to announce her tenure with the group was over already.

“Super disappointed to learn that my time with the Pixies ended today,” she wrote. “Amazing experience. Looking forward to focusing my attention back on the Muffs and our upcoming new album. All the best to everyone.”

There is no word as yet as to who will fill the shoes of Shattuck (you'd wager it'll be someone named Kim), but it won't be long before we find out as the band have a string of US dates scheduled for the early part of next year.

And, here's a Muffs song, because they rule.
