Rob Kardashian underwent emergency surgery at a Los Angeles hospital Tuesday after complaining of stomach pain.

The 'Keeping Up with the Kardashians' star was escorted to the emergency room by his mom, Kris Jenner, where his appendix was removed, TMZ reports.

Luckily, the surgery had no effect on Kardashian's sense of humor. "This is what happens if you don't eat your Wheaties," the 24-year-old wrote on Twitter, sharing a photo of himself recuperating in a hospital gown.
