Demi Lovato insists she is ''fine'' after being rushed to hospital yesterday (24.02.15).

The 22-year-old singer, who was taken to the Providence Tarzana Medical Center in California after experiencing ''significant trouble'' breathing, has assured her fans she is on the mend.

She wrote on Twitter today (25.02.15): ''Thanks for the get well messages..

''I'm fine!! Nothing a little chicken soup can't fix!!''

A source previously revealed the 'Skyscraper' hitmaker was prescribed medication by a doctor after she was found to have a ''flu-related'' lung infection, and was also given an antibiotic known as Z-Pak.

News of her hospitalisation initially sparked concern among her fans, as the singer has often spoken out about the ''dark period'' in her life when she self-harmed, battled depression and eating disorders, and ended up in rehab.

She also admitted in December that she had almost suffered a partial relapse last summer and credited her long-term boyfriend, Wilmer Valderrama, for encouraging her to seek help again.

She said at the time: ''It's been difficult. I almost went back to rehab for my eating disorder last summer. I was obsessing over food and terrified of it at the same time. Wilmer noticed and called me out on it, which was a relief.''
