Kelly Osbourne is attempting to ''strengthen her lungs'' to avoid getting sick.

The 'Fashion Police' host opted for an unusual method to try and combat her cold after she showed off a photo of herself on Instagram using a machine to help improve her lung capacity.

Last night (09.09.14), Kelly wrote: ''Trying to strengthen my lungs With my breathing exercises I'm sick of being sick! (sic)''

The 29-year-old TV presenter recently told her Twitter followers that she was recovering from a bout of pneumonia.

She tweeted: ''When you have a cough go to the doctor or you will end up like me! #Pneumonia (sic)''

In March 2013, the purple-haired fashionista scared her fans after she was admitted to hospital after suffering a seizure.

Her spokesperson later told E! the doctor had issued the starlet with a clean bill of health, adding: ''[The seizure] was most likely a one-time episode of which there are no conclusive results.''

Recently, Kelly has been open about her personal struggles, as she attempts to cope with the passing of her 'Fashion Police' co-host and close friend Joan Rivers, who died on September 4, 2014.

On Monday (08.09.14) an emotional Kelly tweeted: ''Laid down 4 what I thought was a quick nap. Woke up 5 hours later in a pitch black room with no idea where I was #DeepSleep #TiredTears (sic)''
