Kelly Osbourne was hospitalised this weekend when she "cracked" open her head.

The 'Fashion Police' host visited the Mercy Hospital in Miami following the mystery accident, which caused her to keep passing out, and eventually her mother Sharon Osbourne came to collect her.

She wrote on twitter: "I just want 2 thank all the incredible doctors and nurses @ Mercy hospital in Miami 4 taking such good care of me u guys really are amazing!

"Long story short I cracked my head open then kept passing out I have the all clear my mum came 2 get me 4 full story watch the talk tomorrow(sic)"

It is the second injury accident-prone Kelly has suffered recently. Earlier this year, the 27-year-old star broke her foot due to excessive workouts at the gym.

She said: "So, apparently, I've been walking around on a broken foot for weeks without realising something was wrong. My feet always hurt because of my bunions, but started to feel it in my ankle and knee and it turns out I had a couple of stress fractures.

"Running too hard on the treadmill caused me to pull the tendon away from the bone and give myself stress fractures. Now it's just a matter of time until it heals properly and gets back to normal."
