Kelly Osbourne has teeth trouble

Kelly Osbourne - the daughter of Ozzy and Sharon Osbourne - hates people who pick their teeth, saying it makes her feel ''sick''.

The TV star can't stand people with poor personal hygiene, and admits she had a torturous taxi ride with a driver with bad habits. She tweeted, "In a taxi and the driver keeps licking and sucking his teeth and it's making me SICK and putting me in the worst mood."

The 25-year-old blonde - who mainly lives in Los Angeles - is currently in London and admits it's great to be back in her native country.

Kelly - who was born in London, but travelled around as a child on tour with her rocker father Ozzy Osbourne and mother Sharon, who worked as Ozzy's manager - revealed in other twitter posts, "im so happy to be back. even with the bad weather. there is no place like home!!!! (sic)"
