Kelly Osbourne tweets horrendous sunburn picture

kelly-osbourne-sunburn.jpgFresh off debuting her 70-pound weight loss on the cover of Self, Kelly Osbourne reveals that she forgot a key ingredient to enjoying a day in the sun -- sunscreen. Yeouch.

She tweets the above picture, along with the hashtag "I'm smart." Um, yeah.

Osbourne recently had a health scare when she was hospitalized after suffering a seizure. She tells Self, "I never want to take my good health for granted. The seizure was 60 seconds, but those 60 seconds will change my life for the better forever."

Now that you've got the fit, healthy body you've always wanted, perhaps you should protect it from the sun, Kel.
