Jack Osbourne has had his appendix removed.

The 'Adrenalin Junkie' star underwent a surgical procedure to have The Organ taken out yesterday (25.03.12) and posted a photograph of himself in his hospital bed on his twitter page.

Alongside the grainy image of himself and fiancee Lisa Stelly, he wrote: ''This is what you look like when you have had your appendix removed.''

The 26-year-old star - who has previously been in rehab to be treated for an addiction to painkiller Oxycontin - later joked the medication he had been given combined with the music he was listening to meant he was having ''too good'' a time in hospital.

He tweeted: ''Man, high powered pain Killers + Radiohead = Dangerous territory for me. I gotta get outta this hospital. This is getting to good. (sic)''

Jack and Lisa - who got engaged last September after around four months of dating - have been leading a quiet life in the lead up to her pregnancy.

Lisa tweeted last week: ''Jack and I's new hobby is going to cheese stores and buying cheese, salami, olive oils, and finishing salts. Hi, we are officially boring.''
