Miley Cyrus ''can't quit crying'' in hospital.

The 'Wrecking Ball' hitmaker - who was admitted for medical treatment on Tuesday (15.04.14) after suffering a severe allergic reaction to antibiotics - admits she is frustrated at having cancelled two gigs on her 'Bangerz' tour and can't wait to check out of the facility and get back to work.

She tweeted: ''over the hospital. I miss #bangerztour #5amhospyselfie so sleeeeepy #medztime... (sic)''

She later added: ''can't quit crying. i wanna go back on tour. im meant to be onstage performing for y'all.... not laying in a hospital bed (sic)''

Miley - who was left devastated when her beloved dog Floyd died earlier this month - cheered herself up with a video chat with one of her other beloved pooches, Mary Jane.

Posting a screengrab from her phone which showed her dog, she wrote: ''FaceTime with my baby from the hosppppyyy (sic)''

The 21-year-old star is said to be hoping to resume her tour tomorrow (18.04.14) in Nashville, Tennessee.

Explaining her condition, a source said that the former 'Hannah Montana' star was on medication to combat her flu virus and decided to seek medical attention as she felt ''beyond woozy.''
