Alt-grunge dynamo Kelley Deal of the Breeders tweeted a snapshot of her birthday cake in honor of the day she and her twin sister alt-grunge dynamo Kim Deal (the Breeders, the Pixies) escaped the womb. The twins don’t turn 50 until tomorrow, though, so they’ll have to resist the urge to plow into their delectable-looking uterus cake or their sperm and egg cupcakes. According to Kelley, she’s the one on the left, so we can assume that umbilical cord is intravenously injecting her with… life-giving nutrients. Thanks for breeding, Mr. and Mrs. Deal!
