Fans fear for singer as she is rushed to hospital

Singer Demi Lovato is recovering in hospital after being rushed to the ER yesterday with significant breathing difficulties.

The star was brought to the Providence Tarzana Medical Center in California by a friend, and was kept in for monitoring and tests.

Poor Demi was diagnosed with a nasty lung infection and has been given a variety of medication.

Although the Really Don't Care singer has been quiet on social media since earlier this week, Twitter has exploded with "get well soon" wishes from fans, so much so that the hashtag #GetWellSoonDemi has begun trending worldwide.

Demi's illness came at a particularly bad time as she is currently putting together her new album and had to cancel a recording session with a big-name producer, according to TMZ.

The singer recently revealed she thinks her fourth album will be her "best work yet," saying, "I’ve never been more confident in my sound. Never been so sure of who I am as an artist… I WILL get a Grammy nomination one day. No more f*ckin around.”

Demi has been finding her feet again slowly after spending a stint in rehab in 2011 to help her in her struggles with bulimia, self-harm, bi-polar disorder and drug addiction.

In a recent interview the singer admitted that she is on a strict meal plan to help her regain control of her eating habits, but that she has more self-confidence than ever before. "I've learned to appreciate my body for what it is. It helps to remind myself how far I've come," she said.

Wishing Demi a speedy recovery from her lung infection!
