Kelly Osbourne has bronchitis.

The 'Fashion Police' host was hospitalised two years ago with the lung infection and after she woke up yesterday (20.05.13) coughing and spluttering she has been diagnosed by her doctor as suffering from the nasty illness.

Kelly wrote on Twitter: ''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! (sic)''

The 28-year-old star is no stranger to misdiagnosing herself.

In 2011, she thought she had ''just a cold'' but it turned out to be a severe sinus infection and bronchitis, which led to her being put on an antibiotics in 2011.

She tweeted at the time: ''Making soup... I just went to the doctor and found out what I thought was just a cold is a sinus infection and bronchitis.

''The antibiotics im on are kicking my a** i feel like im walking around with weights on my ankles & wrists!

''I tried all natural i hate taking antibiotics but according to my DR (doctor) i almost gave myself pneumonia! i have really really bad bronchitis! (sic)''
