Love him or hate him (and his balloon sculptures), Jeff Koons had a pretty fantastic birthday cake this year, courtesy of his wife, fellow artist Justine Wheeler. “My Picasso ‘Kiss’ birthday cake baked by Justine. My favorite birthday cake ever!” he Tweeted earlier this week. The 1969 painting hangs in Koons’ bedroom (natch). “I think it’s about his conquests in life, his artistic and sexual conquests,” he said in a 2010 interview. (Flashbacks to Koons’ Made in Heaven series.) With a hunger for frosting and sweet, spongy layers of yumminess, we searched for other incredible cakes inspired by the art world.
