Singer and 'Fashion Police' co-host Kelly Osbourne has revealed that she was recently diagnosed with bronchitis and is feeling lousy now that she's on the road to recovery.

Writing on her official Twitter page earlier this week, the star told her 3.1 million followers that she has the infection, but originally thought it was just hayfever:

"Woke up feeling sick so I went to the Doctor & I have bronchitis it sucks I cant stop coughing! I thought I just had allergies!"

Osbourne, who suffered a seizure back in March, returned to the social networking site today and explained that she has been prescribed antibiotics by her doctor, but they're so strong she can't focus on anything:

"4 reasons why I hate being sick: 1. I can't smell anything 2. I can't taste anything 3. I have to keep blowing my nose 4. coughing!!!! I swear to god I have spent the better part of a day staring at the wall the antibiotics the DR put me on are so strong!"
