With Halloween upon us, we caught up with Mr. Bones Pumpkin Patch in West Hollywood, CA, to get more information about the celebrity destination. Famous moms—including Gwen Stefani, Heidi Klum, Jessica Alba (above right), and Christina Aguilera—flock to the spook-filled patch, which is loaded with festive activities like pony rides, petting zoos, straw mazes, and more! Then, of course, there are the pumpkins. Mr. Bones suggests forgoing the traditional perfectly round orange variety in favor of odd shapes, alternative colors (like white or gray), and unique textures for a ghoulish jack-o’-lantern. The star-adored patch also told InStyle.com to "Think stems! A beautiful stem makes a gorgeous pumpkin. If it has curlicues and leaves still attached snatch it up as fast as you can—these are rare gems." Another great gourd tip: "Broken stem? No worries," Mr. Bones assured us. "Make a wicked scary pumpkin by using the stem for a crooked jack-o'-lantern nose. S-P-O-O-K-Y!" Get carving before it's too late, and click through the gallery below to see which other stars were spotted in the pumpkin patch!
